Emily BluntandDwayne Johnsonbecame fast friends on the set ofJungle Cruise— but the two costars still struggled to get a central scene right for the film.

On Wednesday, they sat down withAccessfor an interview about their upcoming Disney film and jokingly said their kiss scene in the film was probably their hardest one to do.

“I literally had to turn to Jaume [Collet-Serra], our director, and said, ‘How many of these do you need?’ " Blunt, 38, said while joking. “I had to get drunk for it.”

Johnson, 49, laughed and said, “Wow,” before adding, “I had to get high for it!”

Filming the movie was “nostalgic” for the pair and the crew, Blunt revealed, as she comparedJungle Cruiseto being similar to other films such asIndiana JonesandRomancing the Stone.

“It was so warm and joyful,” Blunt said of filming. “I think we all felt nostalgic about making it.”

Disney’s upcoming movie finds Blunt’s Lily Houghton, a researcher aiming to find Lagrimas de Cristal, hiring Johnson’s character, Frank, a river guide tasked with guiding her to it.
