Weller later had a small role in the supernatural fantasy Q (1982), written and directed by Larry Cohen.

Weller acted onstage in New York; wrote a play, Four Alone, that was performed at the Greenhouse Theater in Pasadena with a grant from the National Endowment for the Arts; and sought to produce a film based on the life of jockey Mary Bacon before leaving show business. (Weller had trained with the U.S. Equestrian team as a teenager and loved horses; Curtis designs courses for equestrian events.)

Survivors include her cousin Sheila Weller, an author who wrote books including the 2003 family memoir Dancing at Ciro's: A Family's Love, Loss, and Scandal on the Sunset Strip and 2008's Girls Like Us: Carole King, Joni Mitchell, Carly Simon - and the Journey of a Generation.

Asked in 2012 if she knew Animal House would be a success, Weller replied she  was pretty sure  and added:  I remember showing [the script] to Brandon Stoddard, who was head of ABC at that time. He also knew it would be an enormous hit … but he warned me that it would be the movie I would always be known for.
