This episode, filmed in part at the Hollywood Park racetrack, finds Banacek once again being called in to solve the unsolvable. This time it's the case of a 5,000,000-dollar racehorse that went out on its usual morning workout -- and returned as an entirely different horse. Among those questioned by Banacek are guest stars Anne Francis, Tim O'Connor, and Lane Bradbury. Horse of a Slightly Different Color was originally telecast as the January 22, 1974, episode of the weekly Banacek series. ~ Hal Erickson, Rovi
