Cailee Spaeny and Priscilla Presley got a 'spooky' sign from Elvis Presley

Cailee Spaeny and Priscilla Presley received a "spooky" sign from Elvis Presley when they were discussing the 'Priscilla' biopic.

The 25-year-old actress portrays the 'Naked Gun' star in Sofia Coppola's new movie and she's recalled how the 78 year old was stunned to hear her late ex-husband's song on the radio when they were chatting about the project because it happens so rarely.

Cailee told The Hollywood Reporter: "When I was on the phone with Priscilla one time, we were speaking, and then Elvis came on her radio in the background... She [gasped], 'Do you hear that?' And I said, 'What?' And she said, 'He’s on the radio.'

"And then she put the phone up to the speaker, and I think it might’ve been 'Love Me Tender' or something like that. It was one of his slower songs.

"And then I said, 'Does that happen a lot? Does he come up on your radio a lot?' And she said, 'No, he doesn’t.' And then she went, 'Hmm, that’s a bit strange.'

"So that was a very interesting moment and interaction to have with her, as she took that in and reacted to him on the radio.

"I’m sure that’s something we’ve all thought about: How does she feel when she hears him come up again on the radio or TV?

"So I got that firsthand experience with her, and I definitely felt like she thought that was a bit spooky."

Cailee was pleasantly surprised by how "gracious" Priscilla was with her time when she was preparing for the role.

She said: "I wanted her to feel safe and not feel like I was digging into this.

"I wanted her to feel like she could go at her own pace in retelling this story, because I knew that it was probably an emotional thing to relive. So I tried to be careful about that. I wanted her to feel like she was in the right hands and that she felt protected.

"So our first meeting actually went around four hours, which I was shocked about, but she was very gracious with her time.

"I just let things go where they naturally went, and really, the biggest thing for me was just being able to sit in front of her and take her in as a person and the way that she holds herself...

"I got really lucky, just having her support and her saying things like, 'You can call whenever you want. I’m around to talk through anything you need, whether it’s about the movie or anything else. I just want you to know that I’m here.' "
