"I was like, 'I don't know how he will hire me for this job,'" Garner said of speaking with director Matt Shakman.

Audiences got a first look at Garner as Silver Surfer when the trailer was released last week. It features Garner gliding above the city on her floating surfboard. Before the film, the Emmy Award-winner said she familiarized herself with the "Fantastic Four" and "Silver Surfer" comics.

Julia Garner opens up about her role as Silver Surfer in 'The Fantastic Four: First Steps,' which she stars in alongside Pedro Pascal, Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach.
