What it was like to attend the star-studded world premiere of Anne Hathaway and Robert De Niro's new must-see movie, 'The Intern'

The world premiere of Nancy Meyers' "The Intern" was Monday night at Ziegfeld Theater in New York City.

Starring Anne Hathaway and Robert De Niro, "The Intern" is about a startup founder, Jules, who builds a rocketship e-commerce company. Her company, About The Fit, launches a new program inviting people over the age of 65 to apply for a six-week internship.

De Niro plays a 70-year-old widower who no longer enjoys retirement. He applies to the internship and gets assigned to work directly for Jules (Hathaway), who initially wants nothing to do with him.

But as Jules faces increasing pressure both at work and with her marriage, she begins to lean on De Niro and the pair build a strong friendship.

"The Intern" delivers a feel-good plot that people across generations can relate to. It even gets the startup facts right. About The Fit is an 18-month-old Brooklyn startup that seems to model itself after real-life e-commerce companies Nasty Gal and Gilt Groupe. And, like many startup founders, Jules finds her venture capitalists are tough to deal with. Her biggest issues arise when her investors encourage her to hire a more experienced CEO which, as Hathaway's character accurately notes, is an issue both Gilt Groupe's founder and Facebook's Mark Zuckerberg faced.

De Niro and Hathaway nail their performances and had the entire Ziegfeld crowd (which included Mariah Carey and Sting) rolling with laughter, hooting and hollering - particularly during a scene where Hathaway's interns have to break into her mother's home to delete an email Jules accidentally sent.

Other scenes were sentimental tear-jerkers. Nearly all the conflicts in the movie resolve themselves in the end, tying everything up in a nice little bow for viewers. Meyers can count "The Intern" as another win; it's similar in nature to her previous films "The Holiday," "It's Complicated" and "Something's Gotta Give."

"The Intern" is a good pick for families and, even though we were in a biased, high-energy premiere environment, we genuinely liked it.

To sum it up in one word, "The Intern" is cute. You can see it in theaters beginning on Thursday, September 24.
