'Oppenheimer' actor Cillian Murphy had his head glued together after freak accident during filming
'Oppenheimer' also stars Matt Damon, Emily Blunt, Robert Downey Jr. and Florence Pugh
{{#rendered}} {{/rendered}}According to Emily Blunt, "every penny" spent on a Christopher Nolan production goes toward the screen, so his actors shouldn't expect the most luxurious accommodations while filming.
Appearing with her "Oppenheimer" castmates Robert Downey Jr. and Cillian Murphy on ABC's "Jimmy Kimmel Live!" on Thursday, the actress spoke about a freak accident that Murphy had over the course of filming.
Murphy had lost a significant amount of weight to portray the titular character, physicist J. Robert Oppenheimer, and was going to sleep hungry, so Blunt wanted to help make him a bit more comfortable.

"I just felt Cillian needed, probably even more than food, was sleep on this movie. So I got him this very beautiful pillow," she said. "He was really luxuriating in this pillow one night and he woke up in the middle of the night — this is what he told me the next day — and he went to fluff himself back down in the pillow."
"The cool side," Murphy chimed in.

The Irish actor noted that he was waking up in the early hours of the morning to start filming anyway, so he called in the movie's makeup designer for repairs. "She glued my head and covered it all up, and you don't even see it in the movie, I think," Murphy said.

But Blunt admitted there's one thing she and Damon won't do, despite being neighbors.
"I've never read lines with Matt Damon, and I never will," Blunt said with a laugh. "I don’t want your notes or your thoughts, ever," she teased.
