Castle star Nathan Fillion and Private Practice's Tim Daly are hard at work promoting their new animated film Justice League: Doom. And by "hard at work" we mean taking Twitter pictures of themselves dressed in superhero pajamas.

"Justice League "Doom"!!!!!!!!!" Tim recently tweeted, along with a few articles and interviews about his role as Superman.

Nathan, of course, plays Green Lantern, a role he debuted in 2011 in Green Lantern: Emerald Knights.

No tweets yet from Mr. Castle about the movie's upcoming DVD release on February 28, so we're just going to assume he's busy fighting evil … in his undies.
