Foy, 33, wore a glamorous semi-sheer gown by Gucci. The ensemble was black with many different colors in floral arrangements on the skirt and sheer bodice. The top featured a signature Gucci bow. Garfield wore a smart, slim-fit tux.

Breathe is a period drama by Andy Serkis in his directorial debut. The film is premiering at the 61st BFI London Film Festival tonight. The script is by two-time Oscar nominee William Nicholson and tells the true story of Robin Cavendish (Garfield) who was paralyzed by polio at age 28. Against all advice, his wife Diana (Foy) brings him home from the hospital to live out his life, and he surpasses all expectations.

“I always feel a responsibility to any character I’m playing, if people are going to be watching it and they are going to be feeling, and they want to see the truth of what their lives are like reflected back at them,” Foy of playing Diana told The Independent. “…That was hard. I was exhausted. I had several days where I was genuinely bawling my eyes out and then when we had to start acting, I had to go [deep breath] and it was beautiful but really I haven’t recovered, I cry every time I watch it, it’s ridiculous.”

Breathe comes out Oct. 12. See the trailer below.
