Even though it has been 45 years since the death of Elvis Presley, American singer widely referred as "King of Rock 'n' Roll," the 75th Cannes Film Festival kept his spirit alive thanks to an impersonator.

The Elvis lookalike, real name Eryl Prayer, was in town to celebrate the premiere of Baz Luhrmann's biopic which premieres on Wednesday night at the festival.

Fans of Elvis, some of whom were angling for a ticket for the film, were delighted to see Prayer singing in the streets of Cannes, stopping him for selfies and kissing him on the cheek.

Prayer said he first listened to the "Jailhouse Rock" singer when he was in his teens and enjoys returning to his youth through the hitmaker.

"Thanks to Elvis and through him, I bring happiness to people. The image of Elvis withstands the test of time, it's impressive," he told Reuters as he ambled through the French Riviera town.

Lurmann's film, a top festival draw, stars Austin Butler as the titular "Elvis" and Tom Hanks as Presley's enigmatic manager, Col. Tom Parker.

Speaking to one superfan, Prayer said he was glad the film was made because it will bring Elvis and his music to younger generations.
