Since filming X2, in which Shawn Ashmore received a 2005 MTV Movie Award for Breakthrough Male, Ashmore has been busy completing production on two films, in addition to X-MEN: THE LAST STAND. 3 Needles is an indie feature in which he plays a second-rate porn actor in a film about the international AIDS pandemic. The second film, The Quiet, is an independent dramatic thriller.

In September 2005, Ashmore played the title role in Terry, an original movie for CTV about the heroic life of Terry Fox. For his moving portrayal of Terry Fox, a 22 year-old cancer survivor who ran the Marathon of Hope across Canada with one leg, Ashmore received an ACTRA nomination.

Ashmore appeared in the leading role in Earthsea for the SCI FI Channel in the fall of 2004. His career took off in 1994 when he was nominated for a Gemini Award for his work as Waylon Tibbins, the starring role in the TV movie Guitarman. When he was seventeen, he won the role of Jake on Nickelodeon's series Animorphs and worked on the series for two seasons. He immediately followed with the starring role in Disney Channel's In a Heartbeat and just two days after filming the pilot for his new series, director Bryan Singer chose him to play 'Bobby Drake/Iceman' in 20th Century Fox's X-Men.

Ashmore's additional credits include the independent feature Wolf Girl and TV movies Cadet Kelly and Gross Misconduct. Ashmore has guest starred on The Outer Limits and Smallville, in one of the most widely watched episodes.
