What Elvis Presley film is set in England?

"Double Trouble' was a 1967 film starring Elvis Presley as an American singer who crosses paths with a group of criminals in Europe. It ranked as #58 on the list of top grossing movies of that year.

One of the youngest actresses to ever costar with Elvis, English ingenue Annette Day was just 18 years old when she acted in "Double Trouble". Day was discovered in typical Hollywood fashion. Producer Judd Bernard was shopping in an antique store on London’s famed Portobello Road when he caught a glimpse of the red-haired teenager. The shop belonged to Day’s mother, and Day was working behind the counter that day.

Months later, when Bernard was casting for the film, he remembered the perky girl and called on her to ask the fateful question, "Do you want to be an actress?" After a script reading in London and some meetings with MGM executives, Day did a screen test in Hollywood, which satisfied the producers enough to cast her opposite Elvis. Her only prior acting experience had consisted of doing the Charleston in a Christmas concert at school. Elvis did take an interest in Day during filming, though not in the romantic sense. He surprised her near the end of shooting with a white Mustang as a remembrance of her first film experience.
