Robert Coote's last film project.

NBC purchased the television rights to Rex Stout's Nero Wolfe stories for a proposed series that would have starred Orson Welles as Wolfe. Unfortunately, Welles and the network could not come to terms (NBC wanted a weekly series; Welles wanted to do a series of 90 minute movies to be filmed at his home). Ultimately, NBC launched this one-hour Nero Wolfe series with William Conrad in the title role.

Conrad was terrible at memorizing lines so they let him use cue cards.
