Same Year - Almost The Same Movie

The Wizard of Oz and The Blue Bird (starring Shirley Temple) came out within 5 months of each other although The Wizard of Oz was 1939 and The Blue Bird was 1940.The Blue Bird was supposed to be Twentieth-Century-Fox's answer to MGM's The Wizard of Oz. They are quite similar, both teaching that there's no place like home/happiness is to be found at home following a fantasy-based adventure. I like them both but if you watch them both it's obvious why The Wizard of Oz performed better.

Two movies named Jack Frost came out in 1997 and 1998. Both are about a man killed in an accident who comes back as a snowman.

Capote (2005) and Infamous (2006)

One of my old pet peeves was that Rob Roy & Braveheart came out at about the same time. Braveheart was the one celebrated, when it actually was just box office filler, while Rob Roy was a classic.
