She made her film debut – topless – in the 1974 English horror movie Vampira (released as Old Dracula in America). In 1979, Shirriff made her American film debut with a role in the musical drama All That Jazz, which also featured TNG guest star Ben Vereen and DS9 actor Wallace Shawn. That same year, she appeared in a made-for-television movie She's Dressed to Kill, along with fellow Star Trek alumni Joanna Cassidy, John Rubinstein, Clive Revill, and Jonathan Banks.
Shirriff went on to become Jack Palance's first co-host on the original Ripley's Believe It or Not!, staying with the program from 1982 through 1983. And in 1984, she had a supporting role in the drama Covergirl, co-starring TNG guest actor Charles Dennis.
Having retired from acting in the mid-1980s, Shiriff – now Mrs. Catherine Forstmann – is currently a Realtor working in Beverly Hills, California.
