Emma Watson has graduated from Hogwarts in style. She was at every party going over the Bafta weekend. And she certainly caught the eye of Hollywood executives and directors, many of whom would like to work with her. At the W, early Monday morning, Emma was perched on a banquette between Darren Aronofsky and Mark Ruffalo and his wife Sunrise.

Certainly, Aronofsky listened intently to what she had to say, and perhaps he’ll toughen her up in a year or two in a movie about a ballet-loving female wrestler (OK, for you slow ones at the back, he made The Wrestler and Black Swan).

The 20-year-old was still chatting at 4.15am as organisers from the Weinstein studio and Momentum Films were desperate to go home.

The actress, who has played Hermione Granger in the Harry Potter films for half of her life — the last of which, The Deathly Hallows: Part 2, is released in July — has star quality in spades. She has a grace and style that’s rare.

Soon she will go before the cameras to film The Perks Of Being A Wallflower opposite Logan Lerman, while autumn will see the release of Simon Curtis’s film My Week With Marilyn, in which she has a small role opposite Michelle Williams and Eddie Redmayne.
