Michael John McKean, born on October 17, 1947, in New York City, is an American actor, comedian, screenwriter, composer, and musician whose career has spanned over five decades across film, television, and stage. He first rose to prominence as Lenny Kosnowski on the ABC sitcom Laverne & Shirley, a role he played from 1976 to 1983 that made him a household name. McKean’s early television work also included a brief stint as a cast member on the NBC sketch comedy series Saturday Night Live during its 19th and 20th seasons from 1994 to 1995, and he played Gibby Fiske on the HBO series Dream On from 1990 to 1996. His film career began to take shape in the 1980s with roles in Used Cars (1980), the cult classic Clue (1985), and The Big Picture (1989), the last of which he also co-wrote.

McKean is perhaps best known for his long-running collaboration with Christopher Guest, appearing in several of Guest’s mockumentary films. He played the iconic role of David St. Hubbins in This Is Spinal Tap (1984), a satirical rockumentary that has become a touchstone of comedy. He later appeared in Best in Show (2000), A Mighty Wind (2003), and For Your Consideration (2006). For A Mighty Wind, McKean co-wrote the title song, which won him a Grammy Award, and alongside his wife, Annette O’Toole, he co-wrote the song “A Kiss at the End of the Rainbow,” which was nominated for an Academy Award. On television, McKean earned a Primetime Emmy Award nomination in 2019 for his portrayal of Chuck McGill, the brilliant but troubled lawyer, on the AMC series Better Call Saul, a role he played from 2015 to 2018 and again in 2022. Since 2020, he has voiced Lou Pickles in Nickelodeon’s Rugrats franchise. His extensive television credits also include appearances on Curb Your Enthusiasm, Veep, Grace and Frankie, Breeders, and The Diplomat.

McKean has also had a distinguished stage career. He made his Broadway debut in 2004 as Edna Turnblad in the musical Hairspray. He later took on dual roles as J. Edgar Hoover and Robert Byrd in the political epic play All the Way in 2014. His other Broadway credits include the Tracy Letts play Superior Donuts (2009), the Gore Vidal revival The Best Man (2012), and the Lillian Hellman revival The Little Foxes (2017). In a unique achievement, McKean is the twenty-second highest-earning game show contestant of all time, having accumulated $1,115,400 during his appearances on Celebrity Jeopardy!. Throughout his multifaceted career, McKean has demonstrated remarkable versatility, moving seamlessly between comedic and dramatic roles, and leaving an indelible mark on American entertainment.
