The 'Help' star said a bigger hotel room and her own en-suite at the French film festival was one of the biggest perks of her new high profile, reported Contactmusic.
"It's very strange for me because I haven't really noticed the difference. But to compare last year at Cannes and this year at Cannes ... This time I had a nice room. I didn't have to share a bathroom down the hall!," she said.
The actress also said she was once bullied for her looks and called "carrot top" at school.
"I think everybody has a bit of an underdog in them. I remember being the awkward, freckled, red haired girl in elementary school that everyone would call carrot top and then I'd come home crying," Chastain said.
She is best known for her roles in the films "The Debt", "Take Shelter", "Coriolanus", and "The Tree of Life".
