Career
Stanford's first major film role was in the low-budget indie film Tadpole (2002), in which he portrays Oscar Grubman, a precocious 15-year-old with a crush on his stepmother, played by Sigourney Weaver.[4][5] For this performance he earned a nomination for the Golden Satellite Award.

Director Bryan Singer was impressed with Stanford's performance in Tadpole, and cast him as Pyro in the 2003 blockbuster X2, a sequel to X-Men. He continued the role in the third installment, X-Men: The Last Stand, released in May 2006. Both movies are based on the Marvel Comics series X-Men.[7]
Stanford also starred in ABC's midseason replacement Traveler, a drama about two friends who believe they are set up by their good friend (Stanford) to make them look like the conspirators of a terrorist attack.[8]
Stanford appeared in the 2006 remake of Wes Craven's The Hills Have Eyes. He also won the "One To Watch" award at the 2006 Young Hollywood Awards. And in that same year, he starred in the New Hampshire–based comedy, Live Free or Die, playing a wannabe tough-guy criminal named John Rudgate. Aaron also was the voice actor for Pvt.

In 2010, he joined the CW's Nikita as Birkhoff. His character from the film The Hills Have Eyes appears in the 2012 video game Call of Duty: Black Ops II via Zombies Mode.
Stanford played the lead role of James Cole in the television adaptation of the movie 12 Monkeys, which premiered in January 2015 on Syfy.[9] He also was cast in the AMC series Fear the Walking Dead[10] as the recurring character Jim, first appearing in the episode that aired on August 26, 2018.
In 2024, Stanford reprised his role as Pyro in the Marvel Studios filmDeadpool & Wolverine. In an interview with Entertainment Weekly, Stanford said that he was "shocked and thrilled" to get the call to return and also voiced his delight at getting to wear a superhero costume, something he did not get to do in either of his previous performances. "In the original X-Men films, Pyro gets really shortchanged in terms of a costume", he told EW. "In X2 [...] the SWAT team bursts in in the middle of the night and we have to flee. So for half the movie, I'm in my jammies. [...] And in X3, I was just dressed in an ensemble from Hot Topic [...] to have [Pyro] be in a proper superhero costume that was actually taken from the comics themselves was very cool."[7]
