Freddie Prinze Jr.: 1976—: Actor

Perhaps Prinze's most unusual film appearance came with his starring role in the live-action adaptation of the popular 1970s cartoon Scooby-Doo. Dyeing his dark-brown hair blond to take on the role of Frederick Jones, the leader of a group of mystery-solving teenagers, Prinze admitted in an interview with the BBC that "It wasn't very manly, having to get my roots done every week. But other than that it was all right. At the end of the movie my hair was so dead that it literally felt like straw, so I had to shave my head so that something would grow back with some sort of life to it." Hair trauma aside, Prinze was glad that the six-month shoot in Australia for the film allowed him to spend time with Gellar, who co-starred in the movie.

Although the film was derided by critics, Scooby-Doo was the biggest hit of Prinze's career to date. After grossing over $50 million in its opening weekend in June of 2002, the film went on to take in over $150 million in North America alone. For his part in the movie, Prinze earned an estimated $2.25 million. A sequel to the Scooby-Doo movie was announced in 2002; set for release in 2004, the movie would feature Prinze and most of the other original cast members.
