It seems to be a trend with movies, most recently I’ve noticed it with Star Trek Into Darkness, but movies have started to move their dates up to Wednesday instead of the traditional Friday to capitalize on their opening weekend. The Mortal Instruments: City of Bones is the latest to take advantage of the trend.

According to book author, Cassandra Clare on her Tumblr, the release date has been moved up to August 21, and she’s thrilled about it.

I’m really excited because it means the fans will get to see the movie earlier! It also reflects a lot of confidence in the film on the part of the studio to move it to a Wednesday release date so I’m really excited about that, too.

The Mortal Instruments: City of Bones starring Lily Collins, Lena Headey, Jamie Campbell Bower, Jonathan Rhys Meyers, Robert Sheehan, Kevin Zegers, Kevin Durand, Aidan Turner, Jemima West, Godfrey Gao, CCH Pounder and Jared Harris is slated to hit theaters August 21, 2013.
