Curb Your Enthusiasm director Bob Weide was one of the first to break the news of his friend's death, tweeting: "So sad that a sweet friend, kind person & wonderful actress Marcia Strassman lost her brave battle with cancer today."

"She had more friends than anyone in the world," her sister added. "She could do anything. She made clothes, made curtains, knitted sweaters for friends. She could dance."
Strassman's big break came in 1975 when she was cast opposite Gabe Kaplan as his wife Julie in the TV sitcom Welcome Back Kotter. But even prior to that, she had landed a recurring role as nurse Margie Cutler in M.A.S.H.
Her most notable film role was as Rick Moranis' wife in Disney’s hit comedy Honey I Shrunk The Kids and its sequel, Honey I Blew Up The Kids.
Strassman -- who was born in New York City on April 28, 1948, and raised in New Jersey -- passed away after a seven-year battle with breast cancer. She is survived by her daughter, New York costume designer Elizabeth "Lizzie" Collector, and her brother Steven Strassman.
Strassman's sister is asking that in lieu of flowers, donations be made in the actress' name to organizations fighting cancer. Services are pending at this time.
