The theatrical trailer for the Conan the Barbarian reboot has gone online. The film stars Jason Momoa as Conan, with Ron Perlman, Stephen Lang, Rose McGowan, and Rachel Nichols rounding out the cast. While the teaser didn't really show much footage, we really get a sense of what the flick will be like from this trailer. The action actually looks pretty cool, and I'm liking the giant scale and scope of the flick that we're seeing. Momoa certainly looks the part, and I'm definitely intrigued to see more. Directed by Marcus Nispel (The Texas Chainsaw Massacre reboot), the film is set to be released on August 19th in 3D.
