In 1980, one of the ships from movie was recovered in the mangrove swamps of Hillsboro County, FL. A research team from Norway, leas by one Odden Byrd, working with the University of Tampa came in to supervise the salvage and recovery of the boat with the intent of restoring it and sailing it back to Scandinavia, but the boat broke apart and sank while being towed across Tampa Bay.
Star Lee Majors once said it "took a lot of guts" to play a Viking but was persuaded by a fee of $500,000 and 10% of the profits. He later said: "I had a little time off, and they said, "it shoots in Florida, on the coast there, out of Tampa" and they had a bunch of Tampa Bay Buccaneers that were gonna play Vikings, so, I don't know, I thought it'd be fun, so I did it." He also commented: "There is no character to develop here and hardly any dialogue," said Majors, "this is a formula film."
Susie Coelho's outfit in the movie isn't skimpy like the one on the movie poster. On the poster the illustration shows her in a bikini style outfit with her barely covered butt pointed outward, but in the film it's a one piece that doesn't reveal anything but her legs. Writer-producer-director Charles B. Pierce had the artist put her in a sexier outfit and pose to hopefully entice more male viewers.
The film was predominantly shot in Tampa in Florida, USA.
