Once Upon a Crime (1991)

Synopsis
The murder of a millionaire has unexpectedly humorous results in this farcical comedy. When Phoebe (Sean Young) and Julian (Richard Lewis), two Americans on a tour of Europe, discover a lost dachshund, they learn that a $5,000 reward has been posted for the dog's return. Phoebe and Julian head to Monte Carlo to return the pet and claim the money, but they find that the dog's owner has been murdered -- and suddenly, they're suspects in the killing. As hapless detective Inspector Bonnard (Giancarlo Giannini) investigates the crime (imagining that the maid and butler must somehow be involved), he grills several other American tourists he believes are likely suspects, including gambling addict Augie Morosco (John Candy) and loud-mouthed suburbanites Neil and Marilyn Schwary (James Belushi and Cybil Shepherd). George Hamilton appears as an unusually opportunistic gigolo; former SCTV star Eugene Levy directed. ~ Mark Deming, All Movie Guide
