Choose:
Steve Carell - Definitely one of the funniest people around nowadays--I think he'd be AWESOME with the Muppets, even briefly.
Robin Williams - Would make my dream come true.
Jon Stewart - He's done work with the Muppets before, let's get him back in the action!
Jerry Seinfeld - Hilarious, couldn't you just see Fozzie idolizing one of his routines?
Johnny Depp - I have no idea what he could do, but I'm sure he and Gonzo could find something to talk about.
Whoopi Goldberg - Who DOESN'T like her?
Amy Sedaris or Tina Fey (or both) - They just need to be in more things.
Patrick Stewart - He's just incredibly awesome.
Robert Downey Jr. - He's also just incredibly awesome.
Cameron Diaz - Very pretty, very funny, very good choice to work with the Muppets.
Queen Latifah - She's just plan awesome and does very well with the Muppets. I'd love to see a duet with her and Piggy, but we're talking cameos.
Emeril Lagase - Where did the Swedish Chef get off to when the Muppets split...? Can you say assistant to the Bam man himself?
Phyllis Diller - I don't care how old she us, I love her! And I especially love her with the Muppets!
Joan Cusack - Who DOESN'T wanna see her role as Mrs. Bitterman revived?
Charles Grodin - Duh.
Elmo (or any other Sesame Street character) - Please?
Frank Oz - Can you say, "Miss Piggy's limo driver"? Would quite possibly be the coolest thing to happen to anything ever.
Skip:
Halle Berry - No specific reason, I just can't see her working with the Muppets.
Any Sports or Reality Television "stars" - Had to steal it from Super Scoot because it's just SO true.
Mike Myers - Too much of him lately.
Zac Efron - Please... just... no.
Shia LaBuff - This could easily be changed if it's a thoughtful cameo, I just couldn't think of one right now.
Lindsay Lohan - I HIGHLY doubt it would happen, just thought I'd bring it up.
Renee Zelwegger - She just really bothers me.
Nicholas Cage - A fine actor, I just don't see him mixing with the Muppets well.
Samuel L. Jackson - Unless he's poking fun at himself.
Ray Liotta - Talk about tacky.
Hulk Hogan (or any other wrestler for that matter) - I say, if they've been reduced to reality T.V., they're not worthy of this movie.
Ashanti - Let's just never see her again, okay?
Any of the Osbourne family - Same as above.
Phew... sorry that was so long guys.
