He's going from "Twilight" hunk to Greek hero in "Hercules: The Legend Begins," and now we have the first look at what to expect from Kellan Lutz's shirtless take on the classic character.

Ahead of the "Hercules" panel at New York Comic Con, Lutz released a video from the set of "Expendables 3" showing off a quick scene of gladiator action featuring Herc -- with the promise that we'll get to see a full trailer this Saturday.

What's most interesting about this, and a little hard to discern given the lack of footage, is how this conflicts with Dwayne "The Rock" Johnson's similar project, "Hercules: The Thracian Wars." In fact, you'd probably be forgiven for thinking that the Rock's project is a sequel to Lutz's, but it isn't.

Lutz's project is written and directed by Renny Harlin, and will be distributed by Eagle Films in March of 2014. The Rock's Hercules movie is directed by Brett Ratner to be distributed by Paramount Pictures, and will be released on July 25, 2014. And both feature a lot of muscles. Like, a crazy amount.

There's also a difference in subject matter, of course. As far we can guess from Lutz and the Rock's age difference, and the title "The Legend Begins," we imagine Lutz's movie will retell the origin of Hercules. The Rock's flick, on the other hand, is based on a graphic novel of the same name, and details Hercules' life well after he's completed his labors, and almost given up before finding one last chance for redemption during the titular Wars.

No word on whether either actor will be singing "Go the Distance" from the Disney classic "Hercules," but we imagine it will feature heavily in both movies.
