IMDb rates this movie 7.2/10; RottenTomatoes audience score is 70%. This movie is the Suspense tie-in that never happened but almost did. It's included in this web page because of the insight it provides into Suspense history. Papers of Robert Montgomery, hired to be a producer of Suspense in its 60-minute format, were shared with Suspense researcher John Scheinfeld in the 1970s. (Today, Scheinfeld is a highly regarded documentarian and has provided many of his research materials to us). Pitfall was targeted as a potential broadcast, likely near its August 1948 theatrical release, to generate some synergystic publicity for the movie and Suspense. The idea was scuttled when William Spier left Suspense in February 1948 and the 60-minute format was canceled in April 1948. Spier and Dick Powell worked together in the original Rogue's Gallery radio series when it was a summer 1945 replacement for Fitch Bandwagon (unfortunately, no recordings exist). Spier was asked to produce another season of Rogue's Gallery, but declined because of Suspense commitments and those of a new program, Sam Spade. They sought ways to collaborate in radio over the years, but could not find the right situation. Pitfall is another casualty of the ill-conceived hour-long Suspense format. Pitfall was adapted for the 1949-10-17 broadcast of Screen Director's Playhouse.
