Along with director Martin Campbell and producers Donald De Line and Greg Berlanti, Warner Bros. has spent the past five months searching for the actor to play Hal Jordan, the hot-shot Air Force pilot who is chosen by a dying alien to be his successor in an intergalactic police force known as the Green Lanterns.
Other actors in the early mix included Michael Fassbender, Henry Cavill and Jared Leto.
The trade adds that De Line, Campbell and the studio each had a different favorite among the three finalists, making it difficult to come to a consensus.
The studio is targeting a June 17, 2011 release.
