Debuting in Casualties of War in 1989, he is one of several actors whose careers were launched by Brian De Palma. To date, he has appeared in more than fifty films, including three separate films in 2002 that were all nominated for the Academy Award for Best Picture.

Reilly made his film debut in the Brian De Palma film Casualties of War (1989) as P.F.C. Herbert Hatcher. Although the role of Hatcher was written as a small one, De Palma liked Reilly's performance so much that the role was significantly expanded.

John William "Will" Ferrell (/ˈfɛrəl/; born July 16, 1967) is an American comedian, impressionist, actor, and writer. Ferrell first established himself in the mid 1990s as a cast member on the NBC sketch comedy show Saturday Night Live, and has subsequently starred in the comedy films Old School, Elf, Anchorman, Talladega Nights, Stranger than Fiction, Blades of Glory, Semi-Pro, and The Other Guys. He is considered a member of the "Frat Pack", a generation of leading Hollywood comic actors who emerged in the late 1990s and the 2000s, including Jack Black, Ben Stiller, Steve Carell, Vince Vaughn, and brothers Owen and Luke Wilson.

Ferrell was born in Irvine, California, the son of Betty Kay (née Overman), a teacher who taught at Old Mill School elementary school and Santa Ana College, and Roy Lee Ferrell, Jr., a musician with The Righteous Brothers. His parents were both natives of Roanoke Rapids, North Carolina, and moved to California in 1964; Ferrell has Irish ancestry. Ferrell has a younger brother, Patrick. When he was 8, his parents divorced. Ferrell said of the divorce, "I was the type of kid who would say, 'Hey Look at the bright side! We'll have two Christmases.'" The divorce was amicable and both parents were committed to their children. The biggest problem was Lee's line of work. As a person in show business, his paychecks were never steady and he was gone from home months at a time. Growing up in the environment made Ferrell not want to go into show business, but get a steady job.
