This Is 40 was originally scheduled to be released on June 1, 2012. However, in May 2011, Universal moved the film back to December 21 2012, in order to give the June 1 date to their film Snow White & the Huntsman, allowing it to better compete with a rival 2012 Snow White film project, Mirror Mirror, by Relativity Media.
