Mason began his film-acting career at age six when director
Harold Ramis
cast him in
Groundhog Day (1993). Three months later, Mason won the title role in
the hit comedy,
Dennis the Menace (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
Spy Hard (1996) directed by
Rick Friedberg. He also had a role in
Gattaca (1997), directed by
Andrew Niccol, starring
Uma Thurman and
Ethan Hawke.
