Born in Los Angeles, California, Lovitz developed an early interest in comedy and acting, which he pursued through studies at the University of California, Irvine, where he earned a degree in drama. He honed his craft in the improvisational comedy troupe The Groundlings, a training ground for many Saturday Night Live alumni, before being cast on the show. Following his departure from Saturday Night Live, Lovitz transitioned to a successful film and television career, starring as the voice of the acerbic film critic Jay Sherman in the animated sitcom The Critic from 1994 to 1995.

Lovitz's filmography is extensive and varied, showcasing his comedic versatility. He appeared in classic comedies such as Three Amigos (1986) alongside Steve Martin, Chevy Chase, and Martin Short; Big (1988) with Tom Hanks; and the baseball classic A League of Their Own (1992) as a baseball scout. He also took on roles in Mom and Dad Save the World (1992), Coneheads (1993), and Happiness (1998), a darkly comedic film that demonstrated his range beyond broad comedy. In the 2000s, he appeared in Small Time Crooks (2000) directed by Woody Allen, Rat Race (2001), and The Producers (2005), a film adaptation of the Broadway musical. He also voiced characters in animated features like The Brave Little Toaster (1987) and the Hotel Transylvania franchise (2012 and 2015).

On television, Lovitz made memorable guest appearances on iconic shows such as Seinfeld, Friends, and NewsRadio, often playing eccentric or pompous characters that became fan favorites. From 2012 to 2015, he starred in the sitcom Mr. Box Office, and in a notable late-career turn, he portrayed disgraced politician George Santos on The Tonight Show Starring Jimmy Fallon, demonstrating his continued relevance as a political satirist. Lovitz remains active in comedy and acting, frequently performing stand-up and making guest appearances, solidifying his legacy as a distinctive and enduring voice in American comedy.
