Don't Ever Leave Me is a 1949 British comedy film directed by Arthur Crabtree and starring Petula Clark, Jimmy Hanley, Hugh Sinclair, Edward Rigby, and Anthony Newley.

The plot, a variation on The Ransom of Red Chief, revolves around Sheila Farlaine, the teenaged daughter of Shakespearean tragedian Michael Farlaine, who is kidnapped by elderly crook Harry Dentonwhen it's suggested he no longer has what it takes to be a master criminal.

However, in this strange scenario Sheila wants to be kidnapped, as it gives her the opportunity to act grown up and she thinks her father will at last take some interest.

Taking advantage of Clark's vocal abilities, screenwriter Westerby included two scenes in which she sang the tune "It's Not for the Want of Trying" by songwriters Jack Fishman and Peter Hart.

The film, Clark's twelfth, allowed her to play a more mature role than in previous outings, and was both a critical and commercial success.
