Footage of the spacecraft coming to and from Earth was made with both stock and new footage of the Colonial Shuttle from Battlestar Galactica.
The scenes with John Carradine, Tina Louise, and Julie Newmar in the hospital were shot in one day in 1983.
Only main stream film appearances of pornstars Crystal Breeze and Jody Swafford. Producers cast them because they were having trouble finding regular actresses to perform nude. Breeze went fully nude for a sex scene in the woods and Swafford shot a topless scene where she and Traci Escobar rubbed sun tan lotion on each other's breasts by a lake. Escobar was a friend of Swafford's who came along to keep her company. Originally, Swafford was going to be alone in the scene rubbing lotion on herself. Then Escobar volunteered to do it topless because she thought it would be fun to be in a movie. It's her only film appearance. This is adult film star Amber Lynn's first mainstream film, but she made appearances in other mainstream films and shows in her career.
The spaceship in the poster art is the Millennium Falcon from Star Wars: A New Hope (1977), but with a second cockpit added. The ship did not appear in the movie.
