Two main pieces of the casting puzzle for CBS' Supergirl are already in place, with Melissa Benoist set to play the title character, Kara Zor-el, and Mehcad Brooks signing on earlier this week to play photographer Jimmy Olsen. Ever since the project was announced this past fall, fans have been wondering whether or not Kara's cousin, Superman, will have a presence on the show. While the Man of Steel himself has yet to be confirmed, a new report from TV Line reveals that the network is seeking an actor to play the show's main villain, Lumberjack, who has battled with Superman in the DC Comics.

CBS is reportedly seeking a "hulk akin to" Rory McCann, the 6-foot-6 actor who plays Sandor "The Hound" Clegane on HBO's hit series Game of Thrones, for Lumberjack. The character is described as a, "big, burly monster of a man, who has battled Kara's cousin in the past." Lumberjack pops up in the series to test Supergirl's powers, on behalf of an unknown superior villain.

Lumberjack has not been featured on any of the current TV shows based on DC Comics, such as Gotham, Arrow, The Flash or Constantine. Even if Superman doesn't show up, the fact that Lumberjack's battles with Superman are mentioned here, likely means that, at the very least, the Man of Steel will be referenced in the show. If Superman does show up, it will likely be to aid in Kara's development as a superhero, since the series focuses on her finally embracing her abilities at 24 years of age, after hiding her super-human abilities ever since coming to Earth before Krypton's destruction. Who do you think should play Lumberjack in Supergirl?
