Nathan Fillion played T.D.K. in The Suicide Squad and Master Karja Guardians of the Galaxy Vol. 3, but reunites with filmmaker James Gunn for a leading role as the DCU's Guy Gardner/Green Lantern in Superman.
His casting has drawn mostly positive reviews from fans, and we'll discover what Fillion can do as the hero in the Man of Steel's upcoming movie and Peacemaker season 2. The actor is also expected to appear in Lanterns, where he'll join his fellow Sector 2814 Green Lantern Corps members Hal Jordan and John Stewart.
However, that's unlikely to be much more than an extended cameo as the focus will be on Hal and John's dynamic, along with an Earth-based mystery.
Gunn has shared a new featurette for Superman, revealing how Fillion got his bowl cut. As you'll see below, the actor donned a wig which was later styled into Guy's iconic hairdo, though his director couldn't help but have some fun with the weirdness of the situation.
The video ends with a brief clip from the movie. That shows The Daily Planet's Lois Lane angrily suggesting that Guy not having an awful haircut be added to his vows as a member of the Green Lantern Corps. He doesn't appreciate it.
"There was some talk about different hairstyles," Fillion confirmed in a recent interview. "There was some talk about some different types of things we were going to go. I was team bowl cut the whole way. It's canon. It's set. I said, 'If we don't do a bowl cut, we're going to hear about it."
"Now, here's the thing. I have another job [The Rookie] with a boss who's kind enough to let me out for other projects. But I think he would draw the line at a bowl cut police officer," he added.
