The pilot episode of Columbo was directed by Steven Spielberg. Here’s the original TV trailer for the episode originally aired in 1971.
America loves the Mrs. Melville mystery novels penned by the bestselling team of Franklin and Ferris. What America doesn’t know is that James Ferris does all the writing while gregarious Ken Franklin does all the talking ( as in talk shows, personal appearances, books signings ). They have both become rich, but Jim wants to try serious writing on his own. The decision enrages the untalented Ken, who depends on Mrs. Melville to maintain his high style of living. Rather than risk exposure and poverty, Ken resolves to kill his partner and collect on the insurance policy they have on each other. – http://www.columbo-site.freeuk.com/season1.htm
