Dakota Fanning leads Zac Efron, Kristen Bell and a host of young Hollywood stars in a new advert for charity Stand Up To Cancer.
The Change The Odds campaign focuses on the long odds of various unlikely scenarios compared to those of getting cancer.
Aimed at raising awareness in teenagers and young people, the advert reveals odds of one-in-two men and one-in-three women getting cancer in their lifetime.
The Change The Odds advert also features Vanessa Hudgens, Andrew Garfield and Jon Heder amongst others.
Stand Up To Cancer raises funds for cancer research, and will broadcast an hour long live telethon on US television in September.
