His father played keyboards and saxophone for The Righteous Brothers, which was apparently enough to convince him to study sports journalism at USC instead. He trained at The Groundlings after graduating and landed on SNL in 1995. By 2001 he was earning $350,000 a season. The George W. Bush impression, "More Cowbell," the Celebrity Jeopardy sketches. He didn't just play one character type. He became the show's load-bearing wall. He left in 2002 and started working with director Adam McKay on films that somehow made screaming man-children feel like a genre.
The Adam McKay partnership produced Anchorman, Talladega Nights, Step Brothers, and Funny or Die, until McKay cast John C. Reilly in HBO's Lakers series without mentioning it first. They dissolved Gary Sanchez Productions in 2019, and the public breakup played out messily in interviews. Ferrell became primary partner at Gloria Sanchez Productions. His executive producer credits on Succession and Live in Front of a Studio Audience earned him four Primetime Emmys. His 2024 Netflix documentary Will and Harper, about his friendship with trans writer Harper Steele, earned five Emmy nominations and near-universal critical praise. When the Oscars snubbed it, he called the nominators "a bunch of losers."
Growing up with a touring musician for a father taught him what financial instability looks like, so he chose sports journalism at USC as a deliberate hedge against the family business. He wasn't the class clown in high school. He held a school field goal record, captained the basketball team, and did comedy skits over the school intercom with the principal's knowledge. He co-owns LAFC and has run the Boston, New York, and Stockholm marathons. The brand built on screaming middle-aged incompetence belongs to someone who quietly collected varsity letters.
