Zoe Saldana ate lots of green apples before lending her voice to Elio.

Zoe Saldana ate lots of green apples before lending her voice to Elio.

The 47-year-old actress voices the character of Olga Solis in the new Disney Pixar animated film and explained that she snacked on fruit to soften her voice before she worked on the project.

Speaking to Collider, Zoe said: "This is definitely not the first animation that I've voiced, and I feel that I've gotten better at understanding what my voice needs, which is rest the day before and a lot of green apples the day of, because there's something about what green apples do to your palate.

"It kind of softens your taste buds, that way you don't get a pasty sort of sound that, if you're in a booth, can be really loud."

The Oscar-winning star also revealed that she requested to shoot the shouting scenes last so her voice was well-equipped for the emotional scenes.

Saldana said: "Always ask to have all the screaming scenes or lines to be last, that way you get through all the dialogue, all the emotional scenes, and then you get to the ones where you're making a lot of noise."
