ORLANDO, Fla. — Phyllis Thaxter, an actress best known for her role as Clark Kent’s adoptive mother in the 1978 film “Superman,” has died in Florida.

Thaxter’s daughter, Skye Aubrey, says the actress died Tuesday in Longwood after a nine-year fight with Alzheimer’s disease. Thaxter was 92.

The Maine native is credited with appearing in 17 movies. Thaxter also had dozens of television roles, including a four-year run on “Alfred Hitchcock Presents” from 1956 to 1960 and a two-year stint on the “Alfred Hitchcock Hour” from 1963 to 1964.

Thaxter was preceded in death by her husband of 47 years, Gilbert Lea. She was also previously married to film executive James Aubrey.

She is survived by Aubrey and a son, James W. Aubrey.

Her daughter said funeral services will be private.
