On the set of the 1966 sci-fi classic Fantastic Voyage, Raquel Welch portrayed Cora Peterson, a competent technical assistant on a miniaturized submarine crew. The film was a major breakthrough for Welch. It helped launch her into international stardom later that year. Despite playing an intelligent scientist, her experience filming on the 20th Century Fox Studios soundstages was physically exhausting and filled with unique challenges.
Welch wore a white, form-fitting diving suit. The clingy fabric constantly snagged on wires and props. Crew members frequently had to untangle her. To simulate swimming in zero-gravity fluid, actors spent hours hanging from wires. This physical strain led to a genuine near-fainting spell for Welch.
In one scene, the crew defends Cora from attacking antibodies. Director Richard Fleischer had to halt filming. The male actors became far too enthusiastic while pulling the props off her suit. Fleischer noted it looked more like a “Las Vegas showgirl routine” than a medical emergency. Rumors circulated that Welch and leading man Stephen Boyd did not get along well during production. However, their on-screen chemistry anchored the groundbreaking film.
Studio executives initially cast Welch to leverage her athletic physique and screen presence. The film’s massive box-office success, paired with One Million Years B.C. released the same year, launched her into global stardom.
