Christensen is an actor that goes all out for his roles, and he's got the scars to prove it. During his time on set for his 2008 film "Jumper," Christensen told BANG Showbiz (via LondonNet) that "I got a nice scar across my hand, I split my ear open, I knocked my head really badly in this one scene and my pupil got stuck in this extremely dilated position, which was really disconcerting because I couldn't see." It was in this film that he met Rachel Bilson, his long-term partner from 2007 through 2017. Luckily, her on-set injuries were far less severe, as she stated, "I was pretty much injury-free, although I had [a few] bruises and scratches."
Unfortunately, this isn't the only major injury Christensen has experienced. Back in 2001, he acted in a small drama film called "Life as a House." According to Orlando Sentinel, Christensen improved a particularly emotional scene in the film. Once his character Sam learns the truth about his father's health, Christensen punched a wall, resulting in a hairline finger fracture. While that take ultimately didn't make it into the film, Christensen was proud of the moment, telling the Sentinel that "I turned around and I was crying, my hand was bleeding real blood. It was great!"
