'Green Lantern' trailer debuts online

Warner Bros. has released the first trailer for superhero feature "Green Lantern," starring Ryan Reynolds.

Based on the DC franchise, story revolves around a test pilot (Reynolds) who is chosen to save the universe.

Martin Campbell ("Casino Royale") directed the pic. Blake Lively and Peter Sarsgaard also star.

WB showed a serious commitment to the "Lantern" franchise, tapping Michael Goldenberg to write a sequel nearly a year out from the film's release.

The studio is currently prepping two other DC Comics pics: Christopher Nolan's "The Dark Knight Rises" and the Zack Snyder-helmed "Superman," which Nolan is also producing.

"Green Lantern," produced by Donald De Line, opens nationwide June 17, 2011.
