The Wackiest Wagon Train in the West: Four episodes of Dustys Trail (1973) coupled together into a feature film. In a similar situation to Gilligans Island (1964) and even starring Bob Denver again, Dusty is a bumbling assistant to Wagonmaster Callahan. Thanks to Dustys bungling, they are soon separated from the wagon train and lost in the wilderness. The characters parallel those of Gilligans show.
