Years ago I stumbled across a Jack Lemon film called "The Weekenders". It was a bit like Natoinal Lampoon's Vacaton meets the Keystone Cops however I remember laughing a helluva lot.
Another was "The Day Of The Jackal". We'd gone to see "That'll be the Day" but it was sold out so we went to see the Jackal without knowing anything about it. Great suspense movie.
