Universal Pictures has pushed back the release date of “47 Ronin” from November 21, 2012, to February 8, 2013, The Wrap reported.

Filmmakers wanted extra time to work on the 3D special effects, a source at the studio told The Wrap. There have been numerous reports about reshoots and production costs pushing the budget past its original target of $175 million.

The fantasy-adventure film stars Keanu Reeves and is directed by first-time feature director Carl Rinsch, whose background is mostly shooting commercials, music videos and shorts.

“47 Ronin” is based on a Japanese legend about a group of samurai out to avenge their master’s death.
