In A Lonely Place 1950 starring Humphrey Bogart and Gloria Grahame.

In a Lonely Place is a 1950 American film noir starring Humphrey Bogart and Gloria Grahame.
Bogart stars as Dixon (Dix) Steele, a troubled, violence-prone screenwriter suspected of murder. Grahame co-stars as Laurel Gray, a lonely neighbor who falls under his spell. Beyond its surface plot of confused identity and tormented love, the story is a mordant comment on Hollywood mores and the pitfalls of celebrity and near-celebrity, similar to two other American films released that same year, Billy Wilder's Sunset Boulevard and Joseph L. Mankiewicz's All About Eve.
