Mason began his film-acting career at age six when director Harold Ramis
cast him in Und täglich grüßt das Murmeltier (1993). Three months later, Mason won the title role in
the hit comedy, Dennis (1993). He was chosen from twenty thousand other
hopefuls in a nationwide casting call launched by John Hughes and Warner
Bros. It was an early and special opportunity to work with the gifted
Walter Matthau. Mason has had starring roles in such films at Flatland
Pictures' Just in Time (1996) directed by Tom Rice; and Morgan Creek's Bad Moon (1996)
directed by Eric Red, also starring Mariel Hemingway. Among his other film
credits, Mason had a wonderful experience working with Leslie Nielsen in
Disney's hilarious Agent 00 - Mit der Lizenz zum Totlachen (1996) directed by Rick Friedberg. He also had a role in
Gattaca (1997), directed by Andrew Niccol, starring Uma Thurman and
Ethan Hawke.
