Cop in Blue Jeans (1976)

Continuity mistake: The movie opens with a gang of thieves taking the luggage of several Japanese tourists distracted by a guy pretending to defecate on the lawn. One of the robbers is snatching a bright red suitcase in the first shot, which turns into a plain brown suitcase in the next. Also in this second shot one of the bags is lying on the street, while in the previous they were all on the sidewalk. (00:02:40)
