Early life and training

Mattsson was born and raised in Stockholm with her sisters Sofia, Mia, and Cecilia.² In her early teens she was scouted by one of the larger modeling agencies in Sweden.² After graduating from a performing arts high school in Stockholm she went to London and New York to study acting, and at 19 she left London for Los Angeles, where she was cast as the lead in the Warner Bros. comedy Sweden, Ohio (2004).²

An early Swedish press profile placed her in a Hollywood project built around Sweden: the American filmmaker Jason Schulz's The Swedish Princess, in which an American businessman falls for the Swedish crown princess disguised as a waitress. Schulz had first approached the royal court about Princess Victoria taking the part; she declined, and the role went to Mattsson, who played the Swedish princess Anna.⁷

Species: The Awakening. Mattsson's breakthrough came with the fourth film in the Species series, in which she took over the role carried by Natasha Henstridge in the earlier installments.³ The film centers on the young professor Miranda, played by Mattsson, whose life is upended when she learns she is half alien.³ She auditioned five times for the part, then traveled from Los Angeles to Mexico City to film for nearly two months.³ She described the role as her first Hollywood lead in which she played an American, after working to lose her Swedish accent.³

Her subsequent feature credits include Surrogates (2009) with Bruce Willis, Iron Man 2 (2010) with Robert Downey Jr., Seven Psychopaths (2012) with Colin Farrell, and Guns, Girls and Gambling (2012) with Gary Oldman.² In Martin McDonagh's Seven Psychopaths, the ensemble also included Sam Rockwell, Christopher Walken, and Woody Harrelson.⁵
