The 100 Worst Films of the 20th Century A few years ago, the American Film Institute released its list of the 100 greatest American movies of all time, and that gave the folks at TheStinkers.com an idea. With the help of their faithful readers, they compiled a list of the 100 worst films of all time. From the "tired and sloppy" Ace Ventura: When Nature Calls to the "disco dance fiasco" Xanadu, few Hollywood stars are spared. Who can forget Rosie O'Donnell's dazzling big-screen debut in Car 54, Where Are You? or Marlon Brando's piano duet with one of his mutant midgets in The Island of Dr. Moreau? Although we don't agree with the inclusion of the entire Police Academy series (all seven!?), the list pokes fun in all the right places. (in Movies and Film > History)
