Casablanca was shot in two months. It helped that it was shot in a studio, and not on location.

Memento, Christopher Nolan's first hit, was shot in 25 days. Guy Pearce only acted together with the movie’s other principals — Carrie-Ann Moss and Joe Pantoliano — on the first day of filming.

Halloween, John Carpenter's first hit, was shot in 20 days over four weeks on a shoestring budget of $300,000.
