That was over 53 years ago in 1968.
Today she is 76, and has starred in 93 movies in total, 85 since Bullitt was released.
In Bullitt, I think Jacqueline Bisset looks:
Bullitt scores 7.1 out of 10 on The Movie Database.
Jacqueline Bisset's first acting role was as 'Extra (uncredited)' in The Knack... and How to Get It, released in 1965 when she was 20.
