Earlier this week news hit that Warner Bros. was having difficulties with their ad campaign, due to the special effects, for the upcoming Green Lantern movie, as we are about three months out, and all we have so far is the so-so first trailer.

Then we learned that Michael Clarke Duncan most likley will voice Kilowog and that Oscar Award winner, Geoffrey Rush, will voice Tomar-Re.

The big buzz this weekend coming out of the WonderCon, being held in San Francisco, is the nine minutes of footage Warner Bros. released from the Green Lantern movie.

Turns out it was so well received that Warner Bros. has released four minutes of it.

Check it out!

Updated: Two TV spots have been released.

The Green Lantern movie opens in theaters June 17th, 2011 starring Ryan Reynolds as Hal Jordan, Blake Lively as Carol Ferris, Peter Sarsgaard as Hector Hammond, Mark Strong as Sinestro and Temuera Morrison as Abin Sur.
