Dead Men Don't Wear Plaid is a 1982 comedic film noir directed by Carl Reiner and starring Steve Martin as Rigby Reardon, a private investigator who is hired by Juliet Forrest (Rachel Ward) to investigate her father’s death. The film seamlessly integrates footage from classic film noirs of the 1940s and 1950s into its own story. Rigby's investigation leads him to encounter characters played by actors such as Ingrid Bergman, Humphrey Bogart, Cary Grant, Burt Lancaster, and James Cagney, among others. The film's humor stems from its clever use of these classic film clips and Steve Martin's deadpan delivery as the sarcastic and witty Rigby Reardon. Along the way, he uncovers a conspiracy involving a top-secret cheese recipe and a group of shady characters connected to the late Carlotta. The film plays with the conventions of film noir and tongue-in-cheek humor. The audience is kept guessing until the very end about who the real culprits are and what Rigby's relationship with Juliet truly is.
