Casino Royale - 1967

That's right - the fake James Bond movie that also happens to be probably the most awesome one in the series (though this isn't officially a member of the Bond serials). At one point Peter O'Toole walks up to Peter Sellers and asks him if he's Richard Burton. Sellers replies that he is, in fact, Peter O'Toole, to which O'Toole responds: "Then you are the finest man that has ever breathed."

Take that, Roger Moore.

F for Fake - 1975

Without a doubt the finest Orson Welles, possibly one of the finer post-modern films ever made. Also clocking in at just under nine minutes, possibly the longest trailer ever produced.
