The 16-year-old actress is nearly unrecognizable on the set of her upcoming movie, "Three Generations," where she's set to play a New York City teen (Ray) who is transitioning from female to male.
In the pic, the usually-glam starlet is sporting short brown hair, an oversized green utility jacket and a red-brimmed beanie.
We never would have guessed it was the "Maleficient" beauty, if it weren't for her signature smile!
It's unclear if Elle decided to chop off her hair for this role -- we've already seen her rocking some longer brunette locks on the red carpet -- or if it's a wig.
Fanning debuted her darker 'do at the premiere of "The Boxtrolls" at Universal City Walk in September. She paired her new hair color with a more mature look than we're accustomed to seeing from the veteran actress.
"I take a lot of risks. I like to stand out and look unique," she recently told Seventeen.
