Walt Disney hand-picked Lesley for the ingénue role in the 1967 film The Happiest Millionaire, after her Cinderella success. This film was the last live-action movie Disney personally supervised before his death.
Lesley auditioned for the role of Liesl in The Sound of Music.
Lesley was the youngest actor ever to have attended New York's Actors Studio, when she was 17.
Lesley was a student at the School of American Ballet when she switched to acting.
A nice coincidence: Lesley Ann Warren auditioned for the role of Lois Lane in Superman The Movie, 1978, and recently plays the role of Teri Hatcher's mother in Desperate Housewives. The same Teri Hatcher who became famous for playing Lois Lane in the TV show "The New Adventures of Superman".
She also actually played the role of Lois Lane in the 1975 televison adaption of musical "It's a Bird, It's a Plane, it's Superman."
Lesley: Good work is good work wherever it is.
Lesley: I find that there are more interesting roles for women my age in the independent world, which is not to say that there aren't phenomenal roles in studio films, but 99 percent of the time, they go to Meryl Streep or a very short list of women. Very short. And because they want to work as well as we all do, they take them. So now there's not a lot left over.
Lesley: When I was a young girl, I had really long hair and I went to 'Jon Peters' for the first time. He cut my hair within an inch of its life. I was traumatized!
Lesley: Trust your own instincts, go inside, follow your heart. Right from the start. go ahead and stand up for what you believe in. As I've learned, that's the path to happiness.
