Heady states that she was instantly glued to the screenplay. 

She said: "The film has lots of brilliant women in it and it's just fresh and fun and I get to fight, and I'll take anything where that happens! To see women in traditional male roles and unafraid to be violent in terms of survival and righting wrongs is great." 

Even though she looks tough from the outside, her character has many layers, notes Headey, who played Cersei Lannister in 'Game Of Thrones'. 

"Scarlet is riddled with guilt but isn't very good at being vulnerable and with sharing her feelings," she said.
