Was extremely upset at first about her performance as the gangster's moll in Victor Victoria (1982) prior to its release, having thought she went horribly over the top. She did go over the top and the audiences loved her for it. Lesley was nominated for a "Supporting Actress" Academy Award, her only nod so far.
Was fired after only the second day of filming for Devil You Know (2012) due to reported unreasonable 'diva' demands and tantrums. Similar reports were made back in 1997 when Warren wasn't getting star treatment for her Broadway show: 'Dream: the Johnny Mercer Musical Revue'.
Was in a relationship with choreographer Jeffrey Hornaday (1980-1987).
Was originally offered Jean Seberg's role in Paint Your Wagon (1969).
Was student at School of American Ballet when she switched to acting.
Was supposed to play the role of Brenda in Goodbye, Columbus (1969), but she got pregnant and had to be replaced. Ali MacGraw then got the part.
Was very proud of her work in Willing to Kill: The Texas Cheerleader Story (1992) (TV), and was disappointed that it got clobbered by an HBO movie on the same story (The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom (1993) (TV)) that came out at about the same time, starring Holly Hunter.
When she first auditioned for Cinderella, she was so nervous that the audition tanked. She had to audition a second time, and then was hired.

Youngest actor ever to have attended NY's Actors Studio, when she was 17.
