After 12 seasons, the popular comedy "Two and a Half Men" will come to an end this Thursday with an hour-long series finale that may include an appearance from Charlie Sheen.

The title of the episode, "Of Course He's Dead - Part One and Part Two," could be a hint that Sheen will reprise his role as Charlie Harper. Back in 2011, the character was killed off the show after Sheen was fired for publicly bashing the show's executive producer, Chuck Lorre. In response, Sheen filed a lawsuit against Lorre, the network and Warner Brother, the studio behind the show. The leading role was then replaced by Ashton Kutcher.

Last month, Lorre revealed that there is a possibility Sheen will appear in the finale. He also told reporters that he has "nothing but good feelings about those eight and half years" he worked with the actor," reports People magazine.

"The show has morphed into something else entirely for the last four years to something we love," added Lorre, in reference to the casting of Ashton Kutcher. "How to honor both [eras] is the challenge of this finale, and the other challenge [is] how to get people to watch it without telling them what it is."

Actor Jon Cryer remained mum when asked if his former co-star would appear in the series finale.

"I can honestly say I don't know because there were chunks of the finale that I was never allowed to read," Cryer told Adweek. "Nobody got any piece of the script that they didn't 100 percent need, so I have not read the final tag of the show. They didn't even tell me they were shooting it! They shot it on another stage. I've said in the past, the amount of bridge-repairing necessary to make that happen, I thought was incredibly daunting and unlikely, but stranger things have happened in show business."

Cryer did, however, reveal that he hopes to see his character Alan "get rich" or "move out," something to help him "grow up in some way," reports Zap2it. Coincidentally, that may very well happen since Alan's on-again off-again girlfriend Lyndsey accepted his proposal marriage during last week's episode.

The series finale of "Two and a Half Men," "Of Course He's Dead - Part One and Part Two," will air on Thursday, Feb. 19 at 9 p.m. ET on CBS.
