Doc Savage: The Man of Bronze is a 1975 American action film starring Ron Ely as pulp hero Doc Savage. This was the last film completed by pioneering science fiction producer George Pal and was directed by Michael Anderson. The movie received mostly negative reviews.

In 1936, Doc Savage (Ron Ely) returns to New York City following a visit to his top-secret Arctic hideaway, the Fortress of Solitude. He learns that his father has died under mysterious circumstances while exploring the remote interior of the Central American Republic of Hidalgo. While examining his father's personal papers, Doc finds himself the target of an assassination attempt. Doc Savage chases and corners the sniper on the nearby Eastern Cranmoor Building, but the would-be assassin loses his footing and falls to his death. Examining the body, Doc discovers that his assailant is a Native American with peculiar markings; his fingertips are red, as if dipped in blood, while his chest bears an elaborate tattoo of the ancient Mayan god Kukulkan. Returning to his penthouse headquarters, Doc finds that intruders have destroyed his father's personal papers. Vowing to solve his father's murder, Doc Savage flies to Hidalgo with "The Fabulous Five", his brain trust, at his side.

Waiting for Doc Savage's arrival is the international criminal and smuggler Captain Seas (Paul Wexler) who repeatedly attempts to kill Doc and his friends, culminating in a wild melee on board his yacht, the Seven Seas. Meanwhile, Doc's investigation uncovers that, years ago, Professor Savage received a vast land grant in the unexplored interior of Hidalgo from the Quetzamal, a Mayan tribe that disappeared 500 years ago. However, Don Rubio Gorro (Bob Corso) of the local government's land office informs Doc that all records to the land transaction are missing. Doc receives unexpected help from Gorro's assistant, Mona Flores (Pamela Hensley), who saw the original papers and offers to lead Doc and his friends to the land claim.

Following clues left by his father, Doc and his friends locate the hidden entrance into the Valley of the Vanished where the lost Quetzamal tribe lives. Doc separates from the group and finds a pool of molten gold. Doc also learns that Captain Seas is using the Quetzamal natives as slave labor to extract the gold for himself. Meanwhile, Seas' men capture Mona and The Fabulous Five, and Seas unleashes the Green Death, the same airborne plague that killed Doc's father and keeps the Quetzamal tribe under his control. Doc overpowers the Captain after a protracted clash of different fighting styles and forces Seas to release his friends, whom Doc then treats with a special antidote. Seeing their leader captured, the Captain's men try to escape with the gold, but exploding dynamite causes the pool of gold to erupt, covering the henchmen, including Don Rubio Gorro, in molten metal. Freed from Captain Seas, Chief Chaac (Victor Millan) offers the gold and land grant to Doc, who vows: "I promise to continue my father's work ... his ideals. With this limitless wealth at my disposal, I shall be able to devote my life to the cause of justice."

Doc Savage returns to the United States, and at his private rehabilitation center located in Westchester County, New York, Doc subsequently performs acupuncture brain surgery on Captain Seas to cure him of his criminal behavior. Later, during Christmas season, Doc Savage encounters the former supervillain, who is now a bandleader for The Salvation Army, flanked by his former paramours Adriana and Karen. Arriving back at his penthouse headquarters from shopping, Doc hears an urgent message about a new threat that could cost millions of lives, recorded earlier on his telephone answering machine. Doc Savage leaps into action and speeds to his next adventure.

As co-creator of Doc Savage, author Lester Dent retained the radio, film, and television rights to the character as part of his contract with Street & Smith Publications, publishers of the Doc Savage pulp magazine. Although Dent succeeded in launching a short-lived radio program, he was never able to interest Hollywood in a Doc Savage film. Upon Dent's death in 1959, his widow, Norma Dent, acquired the radio, film, and television rights to Doc Savage.

The production team of Mark Goodson and Bill Todman (best known for their many game show productions) announced the intention to produce a Doc Savage film to cash in on the popularity of the re-issued pulp novels by Bantam Books and the James Bond craze sweeping the movies. The film would be based on the July 1934 pulp novel The Thousand-Headed Man, with Chuck Connors as Doc, for a 1966 release. Unfortunately, the producers and Condé Nast Publications, the new copyright owner of the Doc Savage brand, failed to secure the film rights from the estate of Lester Dent. By the time the legal issues had been resolved, the production team and cast had moved on to do the offbeat western Ride Beyond Vengeance.

Only the one-shot comic book movie tie-in published by Gold Key, with cover artwork by James Bama, remains to mark this aborted film undertaking.
