Jessica Chastain just went brunette and she looks so different

We're used to seeing actor Jessica Chastain with her flaming red locks, but the star recently showed off a new look which featured some very different brunette hair.

Jessica was spotted rocking her new look in Toronto, and we can't believe how much of an impact a change in hair colour can make - she looks so different!
Don't worry though, we're sure her red mane will soon return - Jessica is currently filming for Molly's Game so her new look is probably just for the role.

Jessica plays Molly Bloom, an Olympic-level skier and leader of the world's most exclusive high-stakes poker game.
We can't decide which colour suits her best, red or brown!
Check out our favourite redheads, including Jessica, here:
