Universal Pictures has moved the release of Illumination Entertainment's untitled Minions spin-off movie from December 19th, 2014, to July 10th, 2015. So if you were looking forward to seeing the movie, you're just going to have to wait six extra months.
The studio moved it because they were so happy with how well Despicable Me 2 did with its July release date that they are hoping to replicate that success with Minions. Despicable Me 2 has made $840.5 million to date.
I'm sure the movie will do fine regardless of when it's released. Everyone seems to love the Minions.
