Well, I'm not too up on current movies, (we watch a lot of movies on dvd from the library), so can't help with that, but here are some older ones... (The first two we own, and we're pretty picky about only owning things worthy of multiple viewings.)

Noises Off (A local theatre company does a play where things go increasingly and hilariously wrong. John Ritter, Carol Burnett, Michael Caine etc.)

Blades of Glory (Will Ferrell, Will Arnett, Amy Poehler, Jon Heder)

Also, of course a couple really old classics are of course Airplane and Planes, Trains and Automobiles.

Some of the Mr. Bean ones are solid, but I don't remember well enough to quote which titles.

Will try to think of others.
