Yep, its old, 1980, A football player and his friends travel to the planet Mongo and find themselves fighting the tyrant, Ming the Merciless, to save Earth. Its better than it sounds and the soundtrack ( by Queen ) is one of the best ever in a film IMO :-)

It's a science fiction story with the title character as hero. There are several versions of it. Some go way back and appeared in the form of serials. The most recent one I remember watching as a kid and even then I knew it wasn't too good. Some people like it for its campy nature. Here's some information from IMDB: http://spanish.imdb.com/title/tt0080745/ http://spanish.imdb.com/find?s=all&q=flash+gordon

There are several versions of the movie, based on a comic strip by the same name. I'm going to put the entire wikipedia section on this film here, because it says exactly what I was going to say: "The 1980 film Flash Gordon stars Sam J. Jones in the title role, where Flash Gordon begins the film as the quarterback of the New York Jets instead of a polo player. It also features Melody Anderson as Dale Arden, Topol as Dr. Zarkov, Max von Sydow as Ming, Timothy Dalton as Prince Barin, Brian Blessed as Prince Vultan, and Ornella Muti as Aura. Although not a critical success, the film is noted for its musical score, which was composed and performed by Queen. The stand out work is the theme song, "Flash" which many fans consider to be the definitive musical signature of the media franchise. With extraordinarily ornate production designs and costumes by Danilo Donati, and with Dino De Laurentiis as Producer, the film is noted for over-the-top designs and a reputation for being camp, and as such has acquired a cult status amongst students, sci-fi fans, and others. Many of the film's lines are quotable, and often tongue-in-cheek, and this knowing sense of humour contributes heavily to the collective affection with which the picture is remembered. A good example is the performance of the actor Brian Blessed, who 25 years later is still most often remembered by the British public as the Hawkman character 'Prince Vultan', despite many more serious, dramatic roles in film, theatre and television. The plot of the film is based loosely on the first few years of the comic strip, and includes a film version of the famous Alex Raymond Sunday page, "Flight of the Hawkmen"."

The 80's version of this movie was great. Queen did the soundtrack. See it if you get the chance.
