MONTREAL -- It looks like Mila Kunis isn't the only one ready to marry Ashton Kutcher. He's got a date at the altar booked with Jon Cryer too.

Kunis, Kutcher's pregnant finance, doesn't have to worry though -- it's Kutcher and Cryer's heterosexual characters who are getting hitched on this fall's final season of "Two and a Half Men."

Cryer said in a telephone interview with The Canadian Press on Friday that gazillionaire Walden Schmidt, played by Kutcher, is going to go through a crisis and realize the only thing that will give his life meaning is raising a child.

"He's made such a mess of his relationships that he realizes that adopting a child would be the best thing for him," said Cryer.

"In order to do that, he's going to need a spouse and thankfully in California, same-sex marriage is now legal. So who's the guy he knows would never leave him? That would be Alan Harper."

Harper, played by Cryer, has freeloaded his way through the series' 12 seasons, first moving in with his libidinous brother played by Charlie Sheen after getting divorced and then hanging on when Sheen's character was killed off and Kutcher's bought his house.

Cryer will be in Montreal next Wednesday for the Canadian premiere of his new romantic comedy film "Hit By Lightning," where he plays a man whose attempt at online dating goes awry. The film goes into wide release on Oct. 31.

Cryer said it has been "incredibly freeing" to play Alan Harper, who seems to bumble from one personal disaster to the next on "Two and a Half Men," which airs in Canada on CTV.

"He's so flawed and every season he gets a new one, a new, horrible flaw. What's been fun is trying to find the essential humanity and at least striving for him to retain some dignity in the midst of all this.

"When you realize it's not about being good-looking, it's not about the audience loving you, it's freeing. It's like all of a sudden you can go anywhere."

Cryer is looking forward to seeing what lunacy will unfold over the course of the show's final year.

"It's going to be a wild ride."

Wild rides are not unusual for "Two and a Half Men," billed as the longest-running live-action sitcom currently on TV. Despite 30 Emmy nominations -- including two best actor wins for Cryer -- the popular series probably got its greatest attention for Sheen's public meltdown in 2011.

Sheen, who has since gone on to star in TV's "Anger Management," went into rehab and loudly criticized show creator and executive producer Chuck Lorre. At one point production was shut down and Sheen was eventually replaced by Kutcher.

"It's been such a roller-coaster ride on this show -- I don't know if you've heard," Cryer said in a joking reference to the media storm around Sheen's departure. "I won't miss the roller coaster ride but it will have been 12 years of my life. Actors never get that kind of opportunity, to build a character over 12 years."

Describing working on the show as "never boring," he said he enjoyed working with Sheen, who had been with the show since it started.

"He was always good to people on the set. That was never an issue. But we had all grown accustomed to being worried whether we actually had to show up the next day for work. And that slowly eats away at you. It's a weird, constant tension.

"The first week that Ashton was on the show, that was all gone. It was so strange because we didn't realize that we were as frightened about it as we were. The atmosphere has just been different ever since."

Cryer said he'll miss Kutcher and the crew when the show wraps up.

"I'm looking forward to the next thing but incredibly grateful for what has occurred," he said.

"It was never a show that was cool to like," Cryer noted. "The nice thing about that was that was never something we were going for. We were just going for funny and that's kind of freeing in many respects."
