Young Ones is set in the future when water is hard to find and follows a teenage boy (Smit-McPhee) who sets out to protect his family and survive.

Earlier that day, Elle and Nicholas stopped by The Hollywood Reporter Studio to participate in AQUAhydrate’s “Sign for Sundance” campaign, where the brand donates $100 for each celebrity signature received to the Mark Wahlberg Youth Foundation.

FYI: Elle is wearing a Michael Kors top, Louis Vuitton pants and cape, and Bottega Veneta shoes.
