Corrected entry: In the scene where the doctor smashes the glass on the sliding door near the lock when setting up his alibi he correctly does so from the outside but leaves the door open. With the door closed It would have been obvious to anyone seeing where the glass had fallen that the door was open when the break-in was done so making it an inside job.
Columbo: Prescription Murder (1968)
1 corrected entry
Directed by: Richard Irving
Starring: Peter Falk, Gene Barry, William Windom, Katherine Justice
Continuity mistake: At the very end Fleming sees the dead body of his girlfriend being hoisted onto a gurney - she is soaking wet, having been hauled out of the swimming pool. Later we see it is a policewoman acting as a stand-in in order to fool him into talking - and after a few minutes under a blanket on the gurney she, her bikini, and her hair are all bone dry. Not only that, her hair looks like it has just been styled and her makeup is perfect.
Dr. Ray Flemming: They expect me to be on call at all hours.
Lt. Columbo: Same with me, Doctor.
Trivia: The first choice for actors to play Colombo was Bing Crosby.
Correction: You smash the glass and use the hole to open the door. Then you can just walk in there. You do not have to crawl over the splinters.
