Hollywood lost one of its most beloved character actors this morning. Robert Carradine, best known for his iconic role as Lewis Skolnick in the Revenge of the Nerds franchise, has died at age 71.

The news was confirmed by his half-brother Keith Carradine, marking the latest chapter in the storied—and often tragic—history of the Carradine acting dynasty. Robert was the youngest son of character actor John Carradine, whose legacy now spans three generations of performers.

But while the family name carried weight, Robert Carradine never coasted on it. His portrayal of the bespectacled, lovable nerd Lewis in 1984's Revenge of the Nerds didn't just launch a franchise—it helped redefine the underdog comedy for the MTV generation. Before Revenge of the Nerds, nerds were punchlines. After it, they were heroes.

Carradine reprised the role in three sequels, each diminishing in cultural impact but none diminishing his commitment to the character. He understood that Lewis Skolnick mattered to people who'd spent their childhoods being shoved into lockers. That's not nothing.

Beyond the pocket protectors, Carradine built a formidable career in both film and television. He appeared in Martin Scorsese's Mean Streets, showed range in The Long Riders (playing Cole Younger opposite his brothers), and maintained steady work across five decades. More recently, he starred in Lizzie McGuire and had memorable guest spots on everything from King of the Hill to Star Trek: Voyager.

The Carradine family has given Hollywood extraordinary talent—and endured extraordinary loss. Robert's father John died in 1988. His half-brother David Carradine, star of Kill Bill and Kung Fu, died under mysterious circumstances in 2009. Now Robert joins them.

Cause of death has not been disclosed. He is survived by his daughters, including actress Ever Carradine.

In Hollywood, nobody knows anything—except that we just lost one of the good ones.
