Dr. Bart Keppel has a very high opinion of himself. Notwithstanding that opinion, he is being fired by Vic Norris, so Bart plans a murder, constructing a perfect alibi for himself while building evidence against the victim's wife. He kills Vic while running commentary on a promotional short film; but, even in the most perfect planning, there are bound to be some failures, and you can be sure that Lt. Columbo will find them out. Written by

Robert Culp's character of Dr. Bart Keppel wears a green single breasted blazer as one of his costumes. Culp also wore a green blazer in both of his other appearances as the murderer, Paul Hanlon in "The Most Crucial Game" and Investigator Brimmer in "Death Lends a Hand". See more »
Columbo had photos of himself shot to splice them into the 35mm movie print to lure out the murderer. The photos taken are 35mm slides (he shows them framed), and Columbo only states he had them processed and spliced into the film. Problem: Those slides would have to be converted into 35mm cine film frames. 35mm cine film runs vertical as opposed to the horizontal stills camera film. The slides would have to be rotated 90 degrees and reduced in size, with edges chopped to fit into the standard 35mm full frame "academy" aspect ratio. (The movie shown was not wide-screen but rather "academy," similar to standard 16mm or Super8mm.) In the 1970s, test screenings used a mechanically linked soundtrack (either 35mm or 17.5mm with 35mm sprocket holes), as opposed to the final optical (or magnetical) soundtrack-on-film, so the soundtrack and in-sync wouldn't be affected by the splice as long as no frames are missing. This all takes place in LA where all kinds of specialized labs exist, but still, this is a very complex procedure involving highly specialized optical step printer facilities. Can't find those in a matter of hours, not even in LA. See more »
"Double Exposure" is one of the best in this long running series that peaked in the 70's to my opinion. As these films are no whodunnit's, the detective's opponent needs to be a strong character. You bet Robert Culp is one.And he is in top-form as Bart Keppel with his 'subliminal cuts' in advertisement. I think I've seen this one about ten times now and it's still very good entertainment. Note : Culp is also in one or two other episodes, notably in 'The Most Crucial Game'. Brilliant cat-and-mouse-play.
