Thief of Hearts is a 1984 American erotic drama film produced by Don Simpson and Jerry Bruckheimer.

A burglar, Scott Muller (Steven Bauer), teams up with his friend Buddy Calamara (David Caruso), a valet at a high-society restaurant.

Buddy keeps an eye on Mickey and Ray Davis, a rich married couple, while Scott robs their home.

Scott reads the diary and discovers that the wife, Mickey, an interior designer, yearns for a more interesting life.

Mickey's husband, children's book author Ray Davis (John Getz), gets too involved in his work and neglects his wife's needs.

Scott uses his inside knowledge to seduce her, using the pretext of needing someone to re-design his apartment, and posing as a school supply company CEO.

He tells Scott, who, visibly agitated, goes to see Mickey, asking her to leave the city with him, revealing he was the one who stole her diary.

Rather than be arrested for having shot Buddy, he escapes from the police through the window as Mickey watches him running in the dark.

Douglas Day Stewart wrote and directed the film off the back of his successful scripts for The Blue Lagoon and especially An Officer and a Gentleman.

[5] Vincent Canby of The New York Times called it "a good, romantic suspense film that, at its best, has some of the steaminess of Lawrence Kasdan's Body Heat, although a few important plot twists don't stand careful scrutiny."
