Cailee Spaeny was “embarrassed” when she had to undergo augmentation on the set of “Priscilla.”

The 5-foot-1 actress plays Priscilla Presley alongside 6-foot-5 Jacob Elordi as Elvis, and filmmakers went to great lengths to make Cailee appear taller — she had to wear enormous high heels and stand on apple crates, and special catwalks were built into the set of Graceland to give her a few extra inches.

Cailee told NME: “I had these huge, chunky platform shoes – they were also bright pink, which made it even more embarrassing – that I always wore when my feet weren’t in the photo.”

Director Sofia Coppola added: “We had so many apple boxes (on set). We were always trying to make them bigger…

“It fits the story that he is a larger than life character and Cailee and Priscilla are tiny.”

The film tells the love story between Priscilla and Elvis, and Sofia – who both wrote and directed the film – insists she did not want to portray the late music legend in a bad light because of some aspects of the couple’s relationship.

She added: “It’s not about him as an artist. It’s about him privately. So I feel like it’s a completely different side of the same story, which I think makes it even more interesting that people have just thought about the story.”

“Elvis is still present in people’s minds, especially the younger generation. I think this could be a counterpoint.”

“It’s definitely about looking at this mythical couple and showing their human side, and I tried to approach it with sensitivity and be non-judgmental.

“I never wanted him to be a villain.”

Cailee, 25, previously revealed that she really enjoyed working with the acclaimed filmmaker as she was so inspired by her early films.

She told The Independent newspaper: “You have completely changed the way I see myself.

“In her films I saw girls my age who weren’t played by 30-year-olds, who weren’t stupid or naive.

“She doesn’t underestimate young women. Teenage girls are complicated – they have dark sides, passions, desires and fantasies that Sofia understands. Her films gave me permission to explore all those parts of myself. They took away my fear of those parts of myself.”

Sofia’s early films include “The Virgin Suicides” and “Lost in Translation”.
