It was during the filming of this movie that Elvis first met The Beatles at his home in Bel Air on Friday August 27, 1965.
This was one of three Elvis movies released in 1966 (the other two were Frankie and Johnny (1966) and Spinout (1966)). The combined grosses of all three won Elvis the tenth spot on the Quigley Top Ten Money-Making Stars poll for 1966, his final appearance among the top ten.
