Watch: Robert De Niro Goes to Work for Anne Hathaway in ‘The Intern’ Trailer

Robert De Niro plays Anne Hathaway’s 70-year-old intern in the upcoming, aptly titled film “The Intern.” De Niro’s widowed character explains his unorthodox decision in the new trailer, released by Warner Bros. on Monday.

“In retirement, there’s an ongoing relentless effort in creativity,” De Niro says. “I tried yoga, learned to cook, bought some plants, took classes in Mandarin — believe me, I’ve tried everything. I just know there’s a hole in my life and I need to fill it. Soon.”

He fills it by taking an internship at an online fashion site founded by Hathaway’s character (Miranda Priestly would be proud). And of course, the resident sage intern doles out valuable advice to everyone in the office the minute he steps through the door.

Written and directed by Nancy Meyers, the comedy also stars Andrew Rannells, Adam DeVine, Nat Wolff and Reid Scott. “The Intern” hits theaters on September 25.
