i watched a film last night starring:

sean connery
laurence fishburne
ed harris
scarlett johansson

which is 4 quite big stars (although johnasson was only about 8 so she doesnt really count). 4 must be beatable, but i cant think this early, so name some more star studded films.

cameo type films like cannonball run dont really count. oh and dont worry about the films being "good" films.
