ALF's fondness for the old sitcom Gilligan's Island has turned into an obsession, culminating with ALF reconstructing the seven castaways' familiar lagoon in the Tanners' backyard. This inevitably leads to a dream sequence in which ALF meets the Gilligan's Island cast--and learns the hard way that there's a wide gap between sitcom life and real life. Recreating their roles as Gilligan, The Skipper, The Professor and Mary Ann are Bob Denver, Alan Hale Jr., Russell Johnson and Dawn Wells). ~ Hal Erickson, Rovi
