We missed this over the weekend, but apparently MASTODON confirmed what we originally posted last week that they will be working on scoring the 2010 DC-comic adaptation of Jonah Hex staring Josh Broland and Megan Fox.
The band will be working with John Powell and the movie's director, Jimmy Hayward. The band also mentions that guitarist/vocalist Brent Hinds makes a cameo in the film. Sounds like a winner to me!
