- Many of the film productions Mickey and Minnie run through are homages to specific films, such as Godzilla and Ben-Hur. Two of them, a sci-fi film resembling Alien, and a Busby Berkeley aqua-musical in the style of Footlight Parade, are films that were featured in The Great Movie Ride, the attraction being replaced by Mickey and Minnie's Runaway Railway.
