Portrayed by: Carey Mulligan

No disrespect to Carey Mulligan, who plays Irene to great effect in Drive, but she wasn't physically right for the part. Her character, Irene, was written as a Latina woman in her late twenties. When director Nicholas Winding Refn met Mulligan, he felt she was perfect for the part. While Mulligan and Gosling’s chemistry is undeniable, her casting still robbed a Latina actress of what could've been a breakout role.
