It was during the filming of Can-Can in 1959 that she captured the international spotlight. Soviet leader Nikita Khrushchev visited the set of the film and after Prowse performed a rather saucy can-can for the Russian leader, he proclaimed her dance "immoral". Little did Khrushchev know that he was a great press agent, because the publicity brought Prowse considerable attention in the United States. From there, her career took off.
Prowse met Frank Sinatra on the set of Can-Can. Time magazine did not care for the movie but said that Prowse was the best thing in it: "In fact, the only thing really worth seeing is Juliet Prowse, a young South African hoofer who puts some twinkle in the stub-toed choreography".
