I posted just recently that Warner Brothers and DC Entertainment had been dropping the ball when it came to promoting their upcoming superhero action-adventure film slated for this summer blockbuster season. Green Lantern had its first teaser released around November of 2010 and the reception to that trailer was lukewarm at best and dismissal of the film at it’s most vocal.

It’s been almost 4 months since that disastrous attempt at promoting what would be Warner Brothers’ biggest film of the 2011. It looks like Warner Brothers and those in charge of promoting their films may have just learned a valuable lesson in releasing promotion materials when footage needed to spice it up for the target audience is not ready.

WonderCon 2011 at San Francisco has become Green Lantern central as the studios in charge of the film have released not just a kickass official theatrical poster for the film, but a 9-minute sizzle reel for those lucky enough to get a seat in the film’s panel at the Esplanade Ballroom at Moscone Center South. For those who weren’t able to see that 9-min footage the people at Warner Brothers have been gracious enough to release an abridged 4min and 3 second version into the interwebs for everyone to witness.

Even just looking at this abridged version of the WonderCon-exclusive footage has helped in dispelling much of my apprehension towards the success and workability of this film as a live-action blockbuster. The footage goes a long way in setting the tone of the film. Green Lantern has always been part of the cosmic tapestry of the overall DC Universe and the filmmakers seem to have found a way to show that epic cosmic side of the character and do it without making it look cheesy (though some of the CGI effects on the non-human members of the Green Lantern Corps could still use much tuning up).

Except for the part where Jordan is trying to figure out the Green Lantern oath in his living room the footage seems very serious in tone with little comedic beats like the teaser. I would hope that the film does have some comedic beats to it since this is Ryan Reynolds and early Hal Jordan wasn’t always the serious, gloomy gus he turned out later on in his Green Lantern run.

Green Lantern is slated for a June 17, 2011 release.
