Never saw that movie. Like Rosie says, is it bad?
It was a great chance to see some really old actors have another shot at a first run movie. A lot of the stars have died since the movie was made.
Don Ameche, Hume Cronyn, Jessica Tandy, Gwen Verdon, Jack Gilford, Maureen Stapleton, Herta Ware...
Don Ameche was the voice of Shadow in Homeward Bound, but he died before the second one. He was also in Trading Places with Eddie Murphy and Dan Akroyd.
It's not a bad movie; one of the ones in the 80's that showed the aliens as wonderful, peaceful creatures, and most humans as stupid and grasping. But, if you can get past that particular political message, it's a pretty cute movie.
