Jessica Chastain has won the 2013 Golden Globe Award for Best Performance by an Actress in a Motion Picture - Drama for her role as a CIA officer in Kathryn Bigelow's film "Zero Dark Thirty," marking the actress' first win and second nomination.
The winners were announced at a ceremony in Los Angeles on January 13. Chastain beat Marion Cotillard of "Rust and Bone," Helen Mirren of "Hitchcock," Naomi Watts of "The Impossible" and Rachel Weisz of "The Deep Blue Sea."
Chastain became emotional while giving her acceptance speech, citing how she has "auditioned and struggled and fought and been on the sidelines through years."
"I have to thank my grandmother for teaching me to always believe in my dreams and this is an absolute dream come true," she said. "Thank you so much."
"Zero Dark Thirty" depicts the hunt for al-Qaeda terrorist leader Osama bin Laden, who masterminded the September 2001 attacks. The film also stars Taylor Kinney, Kyle Chandler, Jason Clarke, Joel Edgerton and "Sopranos" alum James Gandolfini. Ricky Sekhon plays bin Laden.
This marks Chastain's second Golden Globe nod. She was nominated for both a Golden Globe and an Oscar for her role in the 2011 movie "The Help."
"Zero Dark Thirty" was nominated for four Golden Globes, including Best Motion Picture - Drama, Best Director - Motion Picture for Bigelow and Best Screenplay - Motion Picture for Mark Boal.
