Blake Lively and Ryan Reynolds were at Las Vegas’ CinemaCon on Thursday to promote the upcoming ‘Green Lantern’ movie due for release in June.

After the lukewarm reception the movie trailer received last November, Warner Bros. presented 10 minutes of footage during CinemaCon to show fans that they had a winner on their hands, but also make up for the lack of promotion and advertising in the last few months.

“Part of the reason the response to the first trailer was lukewarm was that the big-scale sequences weren’t ready to show, and we suffered for it,” said Sue Kroll, the studio’s worldwide marketing president, according to the LA Times. “We can’t afford to do that again.”

Ryan Reynolds who will portray the Green Lantern’s Hal Jordan, said he wasn’t worried because he saw the early concepts of the film and saw how well they worked together, but he is ready for the movie which will feature many space scenes, aliens and a lot of 3D visuals.

He told MTV News before the screening, “For me, I just want it out there faster than Warner Bros. can unfortunately produce it. If anyone’s rushing it, it’s me…This movie is a huge project for the studio…There are so many visual-effects shots and so much to do, and it’s just really hard to get ahead of that in terms of a marketing standpoint. That’s no secret. But all that stuff is coming.”

Blake Lively, who will be playing Reynolds’s co-star, Carol Ferris, won the breakthrough performer award of the night at CinemaCon, according to USA Today.  She revealed to MTV that she was a big Comic Book geek, and was thrilled to be chosen to play in the ‘Green Lantern.’ “For me, I was like a kid when I found out I got this [role]. I was like, ‘What kind of stunts am I going to do?’”

She added that she was happy to portray such a, “strong, militant, powerful woman who really challenges Hal. They’re rivals and are always butting heads. She comes in and says, ‘Men are weak too.’ It was just a really special female counterpart in a superhero film,” according to the LA Times’ Hero Complex Blog.
