Nathan Fillion, one of the more fun actors in Hollywood, is a funny, charming, and seemingly genuine person. He can be seen as the lead in "Firefly," Joss Whedon's low-budget but fun space western that felt like a bit of a Han Solo homage, "Castle," as the sarcastic man-child murder mystery writer-turned-detective, and "The Rookie," as LAPD's oldest rookie officer. His time with James Gunn is extensive, as he has appeared in every one of his directorial pursuits in one way or another. He began in "Slither" and "Super" and continued in "Guardians of the Galaxy" and "The Suicide Squad."
In "Guardians of the Galaxy," Fillion appeared as a giant blue alien that tried to bully the new prisoners until Groot put limbs up his nose. He then appeared in the sequel as Wonder Man, only to see the scene cut. In his appearance in the final "Guardians of the Galaxy" film, Fillion shows up as a blundering leader of the security group in the Orgogroup headquarters. Of course, he also appeared in "The Suicide Squad" as one of the most useless on the team, The Detachable Kid.
