Charlie Sheen’s recent rehab stint doesn’t just mean tough times for the actor — or his fellow “Two and a Half Men” cast and crew members.

It might mean long-term trouble for the CBS hit itself even if Sheen returns to the set at the end of February, as has been reported.

That’s because returning to a role where he plays an over-the-top, substance-abusing character — something that mirrors his real life — could be self-sabotaging, according to psychiatrist and author Carole Lieberman.

“If a woman on a soap opera is playing a seductress, that’s not as much pressure as Charlie Sheen playing a character he resembles in real life,” she explained. “On his show, people laugh at that behavior and in some sense encourage it. Yet in his real life, it’s incredibly tragic. There’s that disconnect between what he’s being paid for and what’s destroying him on the other.”

Forgiving viewers
Sheen’s popular character, also named Charlie, has been the subject of laughs on the show since the beginning, and audiences have remained forgiving of his real-life behavior, possibly because of that role. Reruns of the show continue to earn “Men” top ranking in its timeslot, and draw around 11.2 million viewers.

As for Sheen, a November E-Poll Market Research report, which measures the relative marketing effectiveness of celebrities, gave him a very high score — 86 out of 100. (By comparison, his Emmy-winning, more strait-laced co-star Jon Cryer got an 88.)

“That’s pretty amazing,” said E-Poll CEO Gerry Philpott. “(Sheen) gets a far more favorable rating from the general public than most people around.”

“People give stars a lot of latitude; they’re often seen as children,” said Tim Brooks, a former network and cable executive and co-author of “The Complete Directory to Prime Time Network and Cable TV Shows.”

“Also, a lot of people don’t read the tabloids or follow this stuff. They’re busy with their jobs and lives and soccer practice. You’d be surprised just how unaware the public is,” he added.

But Sheen has reportedly chosen to do his rehab from home, a setup unlikely to produce long-lasting results — and there’s a lot of pressure on him to return to work sooner rather than later. That means he may be walking back into work again, playing a laughable man with an addiction, a situation that could provide fuel for another stint in rehab — and hiatus.

This one is already his second in less than a year. The actor went into a month-long rehab stay in 2010 after being arrested for alleged domestic violence after a 2009 Christmas Day fight with estranged wife Brooke Mueller, and the show lost two episodes.

Audiences may not be laughing a third time around.

No Sheen, no 'Men'?
That leaves the show’s writers stuck, as series creator Chuck Lorre has no intention of either recasting the part, or putting in an extended guest-star appearance to hold the spot.

“I can’t see the show surviving without Sheen because of the comedic dynamic,” said an ex-manager with close ties to the show. “And as far as I know, they’re not making any more shows this season.”

Yet this is an unusual situation in the TV world. Film stars like Lindsay Lohan or musicians like Britney Spears may routinely drive their trains off the rails, but TV actors can’t afford to party their nights away.

“It’s more like a job that you come to regularly, and there’s a lot more of a time commitment on the part of the actors,” said Brooks.

The show must go on
TV has had its share of actor disasters throughout the decades, though few have killed off the stars’ series. In 1984, Stacy Keach’s “Mickey Spillaine’s Mike Hammer” had to pause while he served time for drug possession, but the show went on.

On the flip side, even reruns of “Pee-wee’s Playhouse” were yanked when star Paul Reubens was arrested for indecent exposure in 1991. More recently, TV stars including David Duchovny, Matthew Perry and Demi Lovato have all bounced back after rehab stints. Yet few have been as public about it as Sheen.

Networks usually have actors’ backs because no one wants to lose their investment in a scripted series — even when there are tragic circumstances. For example, the suicide of lead Pete Duel in 1971 failed to end the series “Alias Smith and Jones,” then in its first season. Both ABC and producers immediately found a new lead, and the show ran for another two seasons.

But trying to patch up or put on hold a hot show isn’t easy for anyone.

“It’s a terrible dislocation when a show is forced to go into hiatus,” said Gene Ritchings, who served as production coordinator on NBC’s “Law & Order” for 10 years.

“People are thrown out of work in a difficult economy; the writers have to find ways to prepare scripts for an uncertain future. It becomes a knotty problem to work out while they wait for someone’s personal problems to be solved so they can work again,” he added.

Sheen in rehab could cost crew of hit show

“Men’s” crew is likely to get some compensation — during last year’s hiatus they received partial compensation, and many likely work on more than one show. But after 13 episodes each season — and "Men" has already aired 14 of 16 finished episodes — the studio has no legal obligation to pay fellow cast for downtime.

Such details put even more pressure on Sheen to get back to work as soon as possible, which is not exactly a recipe for success, said Lieberman.

Sheen back to work? Not many other options

“He’ll be clean of any drugs quickly,” she said. “But the detox from the substance is just the first phase of rehab. And the more times you go back to your addiction, the harder it is and the more time you need each subsequent time.”

But if Sheen does manage to make it through a legitimate rehab stint, it’s possible that his wildly popular series could be the bigger winner.

“Everything has been so public,” said Adam Hanft, CEO of brand strategy firm Hanft Projects. “If he can battle this with any degree of success, the show may take on an added level of cultural significance — and take its loyal audience to a deeper level.”

Explainer: 5 TV series that lost their leads

    Charlie Sheen may be a huge draw for "Two and a Half Men," but that doesn't mean the show can't do without him of they find the right replacement.

    Charlie Sheen seemingly has his boot on the neck of CBS and Warner Brothers. He can misbehave with porn stars and cocaine all he wants, but he makes so much money for the companies that they can't afford to fire the "Two and a Half Men" star. Right?

    Wrong. It doesn't always work, but as "Charmed," "8 Simple Rules" and other shows demonstrate, some series can afford the departure of their stars provided they find the right replacement.

    It's a lesson Sheen should know well. After all he once served replacement duty himself, stepping in for Michael J. Fox in "Spin City."

    "8 Simple Rules" lost lead John Ritter, right.

    John Ritter's tragic death in 2003 from an aortic dissection forced the producers of the ABC sitcom to scramble to replace its charismatic star. Instead of just replacing Ritter, they opted to go for two for the price of one, enlisting ...

    David Spade and James Garner. The pair joined the series in the wake of Ritter's death. Garner played the deceased actor's father-in-law, while Spade came on board later as a misbehaving nephew. The show though only managed to make it through one and half more seasons.

    David Duchovny left the show after season seven.

    For seven seasons, the dry wisecracks of Agent Fox Mulder (David Duchovny) were considered an essential part of the supernatural Fox thriller's success. However, Duchovny's burgeoning movie career made the actor restless. Hence Agent Mulder's abduction by aliens after season seven and his replacement by...

    Robert Patrick. As Agent Doggett, Patrick faced the unenviable task of assuming the badge of a fanboy favorite. Sure, he had an impressive sci-fi resume having appeared in "Terminator 2," but the ratings took a dive and the show only soldiered on for two more seasons. Tellingly, Doggett wasn't featured in the "X-Files" 2008 sequel "I Want to Believe."

  • 'Charmed'

    After a messy split with "Beverly Hills 90210" producer Aaron Spelling on the hit nineties era drama, Shannen Doherty's casting as the top witch in a sisterly coven was seen as the ultimate hatchet burying. Alas, twas not to be. Doherty left the series after the third season for undisclosed reasons. Flying in on a broomstick to replace her...

    Rose McGowan. The "Scream" star stands as one of the most successful replacements in TV history. Thanks to her macabre sex appeal, "Charmed" was able to cast a spell over viewers for five more seasons.

    Phil Hartman's shocking 1998 murder at the hands of wife Brynn, left NBC's sitcom without its funniest supporting character. Nobody could ever replace the stentorian absurdity Hartman brought to the show, but try the network did, tapping...

    Jon Lovitz. Hartman's fellow "SNL" alum tried to fill his vainglorious shoes as radio host Max Louis. The show plunged from 62 to 77 in the ratings and was cancelled a year later.

    Charlie Sheen. Indeed, the "Two and a Half Men" star should know better than anyone that finding a new star can inject fresh life into even the most successful shows. "Spin City" may not have matched the ratings highs of the Fox years, but it brought Sheen a Golden Globe award and the series stuck around to provide Richard Kind with two additional seasons of employment.
