It was at Aquacade that Williams first attracted attention from Metro-Goldwyn-Mayer scouts.
MGM's head, Louis B. Mayer, had been looking for a female sports star for the studio to compete with Fox's figure skating star, Sonja Henie.
Williams signed her contract with MGM in 1941.

In her contract were two clauses: the first being that she receive a guest pass to The Beverly Hills Hotel where she could swim in the pool every day, and the second that she would not appear on camera for nine months to allow for acting, singing, dancing, and diction lessons.
Williams wrote in her autobiography, "If it took nine months for a baby to be born, I figured my 'birth' from Esther Williams the swimmer to Esther Williams the movie actress would not be much different."

While top stars at the studios such as Judy Garland, Betty Grable, and Shirley Temple took part in bond tours during the war, Williams was asked to take in hospital tours.
At this point, Williams had achieved pin-up status because of the number of photographs of her in bathing suits.
To prepare, Williams and her publicity assistant would listen to Bob Hope and Jack Benny's radio programs, retelling the funniest jokes while at the hospitals.
Williams also invited GIs to dance with her on stage and take part in mock screen tests.
The men would receive a card telling them their lines, and they would act out the scene in front of the other soldiers.
These tests were always romantic scenes to which the men were required to refuse multiple times.
When the men said the final, "No", Williams would pull at her tear-away skirt and sweater leaving nothing but a gold lamé swimsuit.
The scenes would always end with the men giving in and kissing her after that stunt.
Her hospital tours continued into the 1950s.
A (forged) signed, waterproof portrait of Williams was circulated among men in the United States Navy for a "capture the Esther" competition.
This competition continues to this day in the Royal Australian Navy, which holds in its archives an "original" forged signed portrait while maintaining a "capturable" image for use in the fleet.
