Anne Schedeen, best known for playing Kate Tanner on NBC's beloved sitcom ALF, has died at 77. The actress passed peacefully, according to a family statement posted on Facebook. A cause of death was not disclosed.

Schedeen anchored the show's domestic core during its four-season run from 1986 to 1990. ALF centered on the Tanner family harboring an alien life form in their home, and Schedeen's Kate served as the grounded maternal presence keeping the household functioning amid the chaos. The sitcom became a cultural touchstone of the late 1980s, blending physical comedy with creature effects that were groundbreaking for network television at the time.

The actress brought warmth and comedic timing to a role that required reacting to the absurdity of hiding an extraterrestrial in plain sight. Schedeen balanced slapstick humor with genuine maternal concern, making Kate Tanner relatable despite the show's outlandish premise. Her work helped establish ALF as a family-friendly phenomenon that spawned merchandise, animated spinoffs, and lasting nostalgia among Gen X viewers.

Before ALF, Schedeen appeared in shows like thirtysomething and had roles in various television productions. After the sitcom ended, she continued working in television and film, though ALF remained her most recognizable role. The show itself experienced a revival attempt in 2017 with a revival series that never materialized beyond pilot production, though ALF's cultural footprint remained strong through streaming availability and syndication.

Her passing marks another loss for the ALF cast. Paul Fusco, who provided the voice of ALF alongside puppetry from Kevin Seal, and other ensemble members have passed in recent years. The show remains accessible through streaming services, allowing new generations to discover Schedeen's performance and the series
