Craig Ferguson's Robot Sidekick Works 'Red's' Red Carpet (VIDEO)

"Geoff Peterson" can be much more than Craig Ferguson's straight man robot on 'The Late Late Show' (weeknights, 12:37AM ET on CBS). He has red-carpet talent: the ability to catch movie stars off-guard, make them laugh and say things like "I love you" (surely something red-carpet reporters rarely hear from celebrities).

At the 'Red' premiere, Geoff made Richard Dreyfuss ponder this: "Which would you rather -- quail hunting with Dick Cheney or carpooling with Mel Gibson?"

Ferguson had advised John Malkovich to slap Geoff when he visited the red carpet. But after a flimsy tap to his face skull, the two hugged and made up. Sylvester Stallone suggested carbohydrates for Geoff and later remarked to Bruce Willis: "Trouble is, we're gonna end up looking like that one day."

But guess which famous (publicity-shy) actress dissed Geoff?
