Aaron was the son of a symphony musician and a Broadway burnout. Stars whose shine had long since dulled. He wasn't the first child, nor was he the last, but he was easily the most fortunate of the bunch. Early life was defined mostly by piano lessons and singing in the youth choir at church, school plays and puppet shows. There were always things going on, things that would inspire talent and activity. He seemed to have a knack for the piano, much more so than singing, and for some time, it seemed like he would follow in his mother's footsteps as a musician.

He wouldn't have been hailed as a prodigy by any means, but he was very good behind the keys, but the truth was, he had more fun with the plays, even going so far as to do some of the various church plays as well. Even so, his parents pushed him in his musical talents in order to give him a fallback. There were any number of things he could manage to do in the music industry if something caught his fancy, their reasoning was. But that didn't matter to Aaron, not really. He was a kid that knew everything, and the world was his oyster. He would have everything he could ever want and then some. Or so he thought.

But, his father having been a Broadway actor at one point in his life, pressed all the children into auditioning for parts. In Aaron's case, this led to the beginning of his fortune. Before he started in high school, he was lucky enough to land his first role. After beating out numerous other boys for the part, the part of Young Bill Denbrough in Stephen King's IT would be his first step into professional acting. Despite it being a TV movie, it was a film that would be, for many years to come, hailed as the reason people would be scared of clowns. To this, Aaron would laugh and say there was no reason; it was just the same as any other monster under the bed or in the closet - completely harmless.

Aaron wouldn't land any other roles for the rest of his primary schooling. His next one would be shortly out of high school, hitting a minor part in Baz Luhrmann's Romeo + Juliet. It was far from considered to be his crowning achievement, but it was a role he found superbly entertaining, more so that he was given the opportunity to work with some big names. In the following years, he would play a role in the first two I Know What You Did Last Summer movies, in a manner of speaking returning to his roots in horror films.

Not to be typecast in a specific type of film, he ensured his next auditions were for anything but. On a whim, he tried for a role in The Cider House Rules, looking for a change of pace into something a little more meaningful. As luck would have it, he would receive his first major role, as Homer Wells. This film in particular would be of particular interest to him, as it would give him a sort of crash course that he was yet unaware of fully regarding some social lines that had been drawn long ago and never quite erased. It would impact him later in life, in that he would venture into the realm of advocacy for equality.

Soon after, he would take a step back from film, instead auditioning for television parts. He didn't see it as resting on his laurels, so to speak, as much as seeking new opportunities. Eventually, he would be granted a part on the show Six Feet Under. A different sort of drama, his part in this series would only serve to enforce his thoughts on awareness. He put as much effort into this part as he had for any film part, as his character was mentally unstable. Since that time, he has continued to learn about mental illnesses and tried to have greater understanding as a whole.

Near the end of the series, he made another trip into the horror world, landing the leading role in the remake of The Amityville Horror. While he would hear tell that it was a terrible remake, Aaron simply looked at it as maybe not the best role decision he had ever made. However, the following year would present itself with one of the biggest opportunities he would have in his career: Brokeback Mountain.

Ever the socially aware advocate, Aaron jumped at the chance to take the role of Ennis Del Mar. He neither confirmed nor denied any of the rumors regarding himself and his co-star in the movie, but kept his composure regarding it all. To him, it was the perfect role, allowing him to have a chance at portraying a character that was not simply just another heterosexual. It was another film to add to his repertoire of roles dealing with situations of awareness in some form. It was this role that would define him as a person who would try to obtain roles with some meaning to him on a personal level, where he could.

Several of his following roles were either guest or recurring roles on television shows, including Kyle XY and Supernatural, as well as his first role in an animated film, Cloudy with a Chance of Meatballs. Film roles were typically less acclaimed for a few years, until he struck the role of Seneca Crane in The Hunger Games. From that point forward, he made some more television appearances, with the role of Robin Hood on Once Upon a Time and an appearance on American Horror Story. His film roles were a little less involved with social dynamics than they had been before, but he still enjoyed each and every one of his parts, even looking forward to his future roles, as well.
