Anne Schedeen, the actress best known for playing the sharp, no-nonsense mother on the hit NBC sitcom “ALF,” has died. She was 77.

Schedeen’s family announced her death Sunday in a Facebook post, remembering the actress as a funny, forceful and deeply loved presence in their lives.

“She leaves behind an extraordinary legacy of creative energy, whip smart humor, delight in her family, adoration for little dogs, burning hatred for Trump, passion for second-hand thrifting, and love for a good story. We are bereft without her. We loved her so so much, as did all who met her.”

The family added: “She was a force. And it is unimaginable to think about life without her in it.”

Schedeen became a familiar face to millions as Kate Tanner, the matriarch of the suburban family hiding a wisecracking alien who crash-landed in their garage.
