The trailer for Kenneth Branagh's Thor has gone online. It's comprised mostly of the footage that was shown at Comic-Con (and later leaked online), but I think this trailer is better cut together. It's clear that they've done some nifty effects work in the past five months, and I think this is a solid first trailer that will get people interested. It's worth nothing that I've never been one of the people that think the costumes or sets look cheesy. I dig the aesthetic they're going for and it feels like it will be a fresh spin on the superhero genre.

Hit the jump to check out the trailer.  Thor stars Chris Hemsworth, Natalie Portman, Tom Hiddleston, Rene Russo, Idris Elba, Kat Dennings, Clark Gregg, Jaimie Alexander, Ray Stevenson, Joshua Dallas, Tadanobu Asano, and Anthony Hopkins. It opens in 3D on May 6, 2011.

Here's the official synopsis for Thor:

Paramount Pictures and Marvel Entertainment present the epic adventure, “Thor,” which spans the Marvel Universe from present day Earth to the realm of Asgard. At the center of the story is the mighty Thor (Chris Hemsworth), a powerful but arrogant warrior whose reckless actions reignite an ancient war. Thor is cast down to Earth by his father Odin (Anthony Hopkins) and is forced to live among humans. A beautiful, young scientist, Jane Foster (Natalie Portman), has a profound effect on Thor, as she ultimately becomes his first love. It’s while here on Earth that Thor learns what it takes to be a true hero when the most dangerous villain of his world sends the darkest forces of Asgard to invade Earth.
