Character mistake: When Rosie sticks her revolver in Bond's room and Bond flips her onto the bed, Bond incorrectly identifies the gun as a Smith and Wesson .38 which would make it a model 10 or 15. It was actually a Model 19 .357 Magnum.
Character mistake: When Harry walks up to look in the car which Ricca and his men were shot in, he places his hands on the driver's side and back seat passenger's side window sill, while the crime scene is being investigated. No senior Inspector like Harry would do this. (00:09:40)
