In the 1966 film Glass Bottom Boat, Jennifer (played by Doris Day) works in public relations at a NASA facility in Long Beach, CA. While helping her father out with his glass-bottomed boat business, she meets Bruce Templeton, a researcher at the same facility. When Bruce begins to court Jennifer, however, the security chief at the facility suggests that Jennifer might actually be a Russian spy. When Jennifer finds out about this, hijinx ensue. In this short film from Rockwell International, Doris Day simultaneously promotes Glass Bottom Boat and implores employees working on the Apollo spacecraft to be "extra, extra careful." As she explains, when making a movie they have multiple tries to get a scene right, but this luxury does not exist when launching astronauts into space.
