Leslie was in four motion pictures released during 1943. The first was "The Hard Way", starring Ida Lupino and Dennis Morgan. A "New York Times" reviewer described Leslie as "just as deft and versatile a lady as the character she is supposed to be." For the second, she was lent to RKO for "The Sky's the Limit", starring with Fred Astaire. Leslie's character introduced the Harold Arlen-Johnny Mercer song "My Shining Hour". In the third movie, Leslie co-starred in the wartime motion picture "This Is the Army" with Ronald Reagan. The fourth movie was "Thank Your Lucky Stars".
