George Clooney's Wackiest Faces on the Venice Film Festival Red Carpet

See the actor's most ridiculous shots in front of the camera

What ever happened to a good ol' fashioned smile on the red carpet? Apparently, that's just not enough for George Clooney.

The Oscar-winner is busy attending the Venice International Film Festival and it appears the actor is doing a whole lot more than flashing his pearling whites.

While promoting his new movie with Sandra Bullock titled Gravity, the 52-year-old hunk appeared to be having a blast on and off the carpet.

As he walked hand-in-hand with his sexy costar, the actor provided quite the show for photographers as he laughed at jokes, mugged at the photogs and even asked one person to wait one minute.

With Bullock by his side, should we really be surprised to see the actor's hilarious antics?

As Clooney tries to keep it professional, (Hey, he is single and one of People's sexiest men alive) we've decided to compile all of the actor's wacky and crazy facial expressions.
