Meryl Streep Signs Up For 'Stuck On You' Cameo

"Somewhere along the way, we bumped into Meryl and she told us that she always wanted to do comedy and to please keep her in mind," Bobby told the Track. "And we thought, `What do we do with Meryl? What do we do with Meryl?' So we decided to have her play a comedic version of herself."

So Streep will play Streep in a scene where the joined-at-the-hip twins - who travel from their home on Martha's Vineyard to Hollywood because one of them wants to be a star - are in a production of "One Flew Over the Cuckoo's Nest." Meryl plays Nurse Ratched.

"We are kind of winging it as we go along," Farrelly said. "Because we don't have the rights to `Cuckoo's Nest' yet. But hopefully, we'll get them. If not, we'll have Meryl in something else. You know the old saying, `You don't bring a gun onstage and not use it.' "

Oh, no. If Meryl's agreed to work with the guys responsible for cheesy classics like "Shallow Hal" and "There's Something About Mary," the Oscar gal won't be left on the cutting room floor!

And guess what? Meryl's not the only famous face who will stick her mug in "Stuck." Cher has also signed on to play a lead role.
