The 5 Funniest Movie Cameos

Movie cameos can be clever, serious or poignant and then many others can be very, very silly. Sometimes stars can make fools of themselves, popping up in silly films and being very silly. With Scary Movie 5 fast approaching and promising embarrassing entries from all sorts of has-beens, I thought I'd take a quick look at some of the best movie cameos that have made me almost rolling on the floor laughing.

Edward Norton in The Invention of Lying as a cop with a coke habit. Cameos are always funniest when a 'serious' actor is willing to get very, very silly.

Martin Sheen in Hot Shots Part Deux. Blink and you'll miss it as the Sheens pass each other on boats and get the opportunity to compliment each other on finer moments in their careers.

Robert Patrick in Wayne’s World 2. For fans of Terminator 2 (and let's face it, who isn't?), this one is utterly hilarious. I just wish the T-1000 had broken into a run at the end of this clip.

Tom Cruise in Tropic Thunder. Will Les Grossman get his own spin off film? I for one hope he doesn't. A little bit of Grossman goes a long way.

Bill Murray in Zombieland. Instantly classic. If they do get round to making a sequel, it will take someone pretty special to top a cameo of this silliness.

I wonder what Anchorman 2 will have to offer and if they can top the likes of Tim Robbins in the sequel? What are your favourite funny movie cameos?
