Jaimie Alexander (born March 12, 1984) is an American actress best known for portraying Jessi on the TV series Kyle XY and Sif in the 2011 superhero film Thor.
Her career was launched in 2003 when she was cast in the leading role of Hanna Thompson in the low budget award-winning film, The Other Side (2006/I). According to the movie's commentary, she was originally at the audition to help out by reading against the male actors, but the director Gregg Bishop decided to cast her in the leading role after hearing her perform the lines. Alexander’s first role was in the movie Squirrel Trap where she played 'Sara', the love interest of the main character, David, who is a socially introverted genius portrayed by Keith Staley. This was soon followed by a guest appearance in It's Always Sunny in Philadelphia, where she portrayed a femme fatale in the role of 'Tammy', who through a combination of seduction and threats manipulates one of the main characters. She also has a small part in an episode of Standoff.
From there she proceeded to more significant roles. She appeared in the movie The Other Side as 'Hanna Thompson', the girlfriend of the main character; and in the series Watch Over Me where she portrayed the controversial character of 'Caitlin Porter'.
In 2006, she had her first lead role in the horror film Rest Stop where she portrayed 'Nicole Carrow', a girl who escapes from home and goes on a trip with her boyfriend, which is unexpectedly interrupted at a rest stop by a deranged serial killer. In 2007, she had her second lead role, also in a horror film. In Hallowed Ground she played 'Elizabeth Chambers', a girl stranded in a small town inhabited by a sect that plans to use her as a vessel for the rebirth of their founder. In both movies, her character is a strong character who fights back against her aggressors.
Her most famous part so far was that of 'Jessi' on the ABC Family television show Kyle XY. She portrays a girl with superhuman powers who is trying to find her way in the world, with increasing cooperation and eventual romance with her male counterpart Kyle. Her role generated a large fan base hoping to see a spin-off show for her character. She also has had guest roles on the show CSI: Miami where she played 'Jenna York', a flight attendant involved in a murder case; and in Bones where she played 'Molly Briggs', a student connected to the victim of the episode.
In September, 2009, it was reported that Alexander will portray Sif in the upcoming live-action superhero film, Thor directed by Kenneth Branagh.
In July 2010 it was reported that Alexander had been cast in the independent comedy-drama film, Loosies co-starring Peter Facinelli and directed by Michael Corrente. In October 2010 it was reported that Alexander joined the cast of Nurse Jackie in a sizeable story arc as Jackie’s (Edie Falco) wild, immature sister-in-law, Tunie Peyton.
Alexander will appear in the upcoming film Savannah directed by Annette Haywood-Carter about Ward Allen (Jim Caviezel), a real-life early 1900s aristocrat who starts an unexpected partnership with Christmas Moultrie (Chiwetel Ejiofor), a freed slave.
