The Underdog Choice
Like Boreanaz, he’s primarily known for his TV work, but unlike his fellow Joss Whedon star, he’s also made the leap to movies with the likes of Slither, Waitress and Serenity. He’s got charm to spare and anyone who saw web comedy musical Dr Horrible’s Sing-A-Long Blog can attest that he can take on a superhero part.
For all his Whedon-exposure, he’s not a big name. Still, maybe his stint voicing one of the leads in the animated Wonder Woman will endear him to Warners. Doubt Campbell would cast him, though.
