'Two and a Half Men,' the reboot, premieres tonight (Mon., Sept. 19, 9PM ET on CBS), and I've got details on returning faces and dream guest stars, straight from the cast.

I sat down with stars Jon Cryer, Angus T. Jones and new addition Ashton Kutcher on the show's set -- see part one of my interview with them here -- to try to get some scoop on the new season. We know Charlie Harper (Charlie Sheen) is obviously out, we keep hearing about a funeral for his dearly departed character and we've seen some photos of his old flames making a return, including Jenny McCarthy.

But what other familiar faces are stopping by the show again this season? "Welcome back, Judy Greer," Cryer said, about the multi-talented actress' return to the show in an entirely new role. "She was too good to only use as one person on this show."

"She's brilliant, and I think she's fantastic," Kutcher gushed about his old pal, who'll be playing his ex. "We've been having a lot of fun ... she's really funny."

Courtney Thorne-Smith, who played Alan's girlfriend Lyndsey last season, will also be coming back for more. "She's pretty," Cryer chimed in.

But going into the ninth season, is there anyone they want to have on the show that they haven't gotten yet? "You know who I think would be awesome?," Kutcher asked. "To have Mark Zuckerberg on the show." "I don't even know who that is," Jones said about the Facebook inventor and billionaire, inciting some shocked reactions from his co-stars and a little debate.

"I'm not sure if he invented it, because the Winklevii may well have invented it, and then he stole it," Cryer joked, recapping what we all learned from 'The Social Network.' "You sure you want to take that side, my friend?"

"I've met the Winklevosses," tech guru Kutcher said with a laugh. "I'm taking that side."

Watch the video to see who else they'd love to have on, and what exactly the rules of Kutcher's much-publicized mega-trailer are.
