Flash Gordon is a 1980 space opera film directed by Mike Hodges, based on the King Features comic strip of the same name created by Alex Raymond. The film stars Sam J. Jones, Melody Anderson, Ornella Muti, Max von Sydow and Topol, with Timothy Dalton, Mariangela Melato, Brian Blessed and Peter Wyngarde in supporting roles. The film follows star quarterback Flash Gordon (Jones) and his allies Dale Arden (Anderson) and Hans Zarkov (Topol) as they unite the warring factions of the planet Mongo against the oppression of Ming the Merciless (von Sydow), who is intent on destroying Earth.

Producer Dino De Laurentiis, who had previously overseen two other comic book adaptations, Danger: Diabolik and Barbarella (both 1968), had held an interest in making a Flash Gordon film since the 1960s. After a directorial offer from George Lucas was declined (resulting in the creation of Star Wars) and a version that was to be directed by Federico Fellini did not enter production, De Laurentiis hired director Nicolas Roeg and Enter the Dragon writer Michael Allin to lead development on the film in 1977, but replaced them with Hodges and Lorenzo Semple Jr., who had scripted De Laurentiis' remake of King Kong, due to his dissatisfaction with Roeg's vision for the film.

Flash Gordon was primarily filmed in Britain, including on several soundstages at Elstree and Shepperton Studios, and uses a camp style similar to the 1960s TV series Batman (which Semple developed). Due to a dispute with De Laurentiis, Jones left the film prior to the end of principal photography, resulting in much of his dialogue being dubbed by actor Peter Marinker; the circumstances of Jones' departure from the project and his career in the aftermath of its release serve as the key subjects of the documentary Life After Flash. The film is notable for its musical score by the rock band Queen, featuring orchestral sections by Howard Blake.

Although a box office success in both the United Kingdom and Italy, Flash Gordon performed poorly in other markets. Critical reception during and since the film's initial release has been generally favorable, and it has since gained a significant cult following.

DETAILED PLOT

To relieve his boredom, Emperor Ming the Merciless of the planet Mongo declares that he will play with and destroy Earth by remotely causing natural disasters. On Earth, New York Jets football star Gregory "Flash" Gordon boards a small plane, where he meets travel agent Dale Arden. Mid-flight, the cockpit is hit by a meteor and the pilots are lost. Flash takes control and manages to crash land into a greenhouse owned by Dr. Hans Zarkov. Zarkov believes that the disasters are being caused by an extraterrestrial source pushing the moon towards Earth, and has secretly constructed a spacecraft that he plans to use to investigate. Zarkov's assistant refuses to go, so Zarkov lures Flash and Dale aboard. The rocket launches, taking them to Mongo, where they are captured by Ming's troops.

The trio is brought before Ming, who orders Dale be prepared for his pleasure. Flash tries to resist, but is overpowered. Ming orders Zarkov be reprogrammed and Flash executed. Ming's beautiful daughter, Princess Aura, seduces Ming's surgeon into saving Flash, with whom at first sight fall in love. As they escape, Flash sees Zarkov being brainwashed by Klytus, the metal-faced head of the secret police. Aura and Flash flee to Arboria, kingdom of Prince Barin. En route, Aura teaches Flash to use a telepathic communicator to contact Dale. He lets her know he is alive, while Aura starts kissing him. Dale is locked in Ming's bedchamber but, encouraged by Flash, she escapes. Klytus sends Zarkov to intercept Dale, who tells him and Klytus that Flash is alive. Zarkov then reveals he resisted the brainwashing, and escapes Mingo City with Dale. They are quickly captured by Prince Vultan's hawkmen and taken to Sky City.

Aura and Flash arrive at Arboria. Aura asks the Prince to keep Flash safe. A distrustful Barin, in love with Aura, agrees not to kill Flash, but then forces him to perform a deadly ritual. Barin and Flash take turns sticking their hands into a hollow stump with a giant scorpion-like wood beast inside. When Flash has to take an extra turn, he pretends to be stung as a distraction and escapes. Barin follows, but they are both captured by the hawkmen.

Klytus informs Ming that Gordon's alive and is given authority to find the responsible party. Aura returns and is taken prisoner and tortured by Klytus and General Kala. They force her to confess and Ming orders her banished to the ice moon Frigia once his wedding to Dale has taken place. Meanwhile, Flash and Barin are taken to Sky City, where Flash and Dale are briefly reunited. Flash is forced to fight Barin in a death match, but Flash instead saves Barin's life, causing Barin to join him. Klytus arrives, and Flash and Barin kill him. Knowing this will bring retribution, Vultan orders the hawkmen to evacuate, leaving Barin, Flash, Dale and Zarkov behind. Ming's ship arrives and he orders Barin, Zarkov and Dale to be taken aboard. Ming is impressed with Flash and offers him lordship over Earth in exchange for loyalty. Flash refuses and Ming gives the order to destroy Vultan's kingdom along with Flash. Flash finds a rocket cycle and escapes before Sky City is destroyed.

Flash contacts Vultan, who is hiding on Arboria, and they plot an attack on Mingo City. Flash pretends to attack Mingo City alone on his rocket cycle. General Kala dispatches the war rocket Ajax to kill Flash, but the hawkmen ambush and seize the rocket. Meanwhile, Princess Aura overpowers her guard and frees Barin and Zarkov from the execution chamber. Flash and the hawkmen attack Mingo City in Ajax and Kala activates the defenses as Ming's and Dale's wedding begins. Mingo City's lightning field can only be penetrated by flying Ajax into it at a suicidal speed. Flash volunteers to stay at the helm to ensure success and enable the hawkmen to invade the city.

Barin and Zarkov enter the control room and confront Kala, who refuses to cooperate. She attempts to kill Zarkov, but Barin shoots and kills her. Barin tells Zarkov to hold the fort while he heads to Sector Alpha 9 to deactivate the lightning field. Zarkov tries, but is unable to deactivate the shield from Kala's control room.

Barin fights through Ming's guards and gets to Sector Alpha 9 and deactivates the lightning field before Ajax hits it. Flash flies the rocket ship into the city's wedding hall and the ship's bow impales Ming. He drags himself off the rocket nose, seriously wounded, and Flash offers to spare his life if he will stop the attack on Earth. Ming refuses and attempts to use his power ring on Flash, but his power falters and nothing happens. He then aims the ring at himself and is seemingly vaporized by its remaining power, seconds before the counter to the destruction of the Earth reaches zero. A huge victory celebration ensues.

Barin and Aura become the new leaders in Ming's place. Barin names Vultan the general of their armies. Flash, Dale and Zarkov discuss returning to Earth. Zarkov says he doesn't know how they will get back, but they will try. Barin tells them all they're welcome to stay, but Dale says she's a New York City girl, and it's now too quiet around Mongo.

The final frame shows Ming's ring being picked up by the hand of an unseen person. Ming's evil laugh echoes as the ending credits roll. Following the credits, the text "The End" is shown on the screen before a question mark (?) is appended.
