Dark Passage (1947)

Bogart plays a man convicted of murdering his wife who escapes from prison in order to prove his innocence. Bogart finds that his features are too well-known, and is forced to seek illicit backroom plastic surgery. The entire pre-knife part of the film is shot from a Bogart's-eye-view, with the viewer seeing the fugitive for the first time as he starts to recuperate from the operation in the apartment of a sympathetic young artist (Bacall) for whom he soon finds affection. But what he's really after is revenge.
