Green filmed scenes for the 1992 Buffy the Vampire Slayer movie, but they were eventually cut out. However, Green can still be seen on the home video box. Along with Chi Muoi Lo, he is one of only two actors to appear in both the original film and the television series.
In the late 90s/early 2000s, Green earned greater acclaim after appearing as Dr. Evil's son Scott in the Austin Powers trilogy.
Green also voices the character of Chris Griffin on the animated comedy series Family Guy and is one of the creators and producers behind the stop-motion animation comedy series Robot Chicken.
