There’s a good amount of film noir in the Internet Archive Top 100, but I think this is the only film noir parody. The story is told in flashback as Bob Hope, as a baby photographer, relates how he was caught up in a world of mistaken identity and subterfuge. Peter Lorre and Lon Chaney provide the humorous menace, and with Dorothy Lamour as the love interest, you might be able to guess who appears in a cameo.
The IMDb’s users don’t give comedies the high rankings they give more serious films. Adjusted for that, plus Leonard Maltin’s endorsement, it’s enough to keep this fun movie in the top 30.
