Emma Watson will obviously always hold her breakout role close to her heart no matter what characters she goes on to play, a fact she鈥檚 made clear with her current transformation into the heroine of Beauty and the Beast. Since the announcement of her new starring role, Watson has revealed a connection between the two fan favorites of Hermione and Belle, as well as a Harry Potter Easter egg that鈥檚 been dropped into the film鈥檚 intro song that you might have otherwise missed.

It鈥檚 a momentum the A-list actress has kept going even post-production. In the midst of her world-wide tour premiering the new live-action Disney movie, she wanted to include her Harry Potter cast-mates. Assembling the crew of busy international actors, however, is no easy feat. As Matthew Lewis (AKA Neville Longbottom) told People, 鈥淲e had like a WhatsApp group, and she invited a whole bunch of us all over the place.鈥

It definitely makes sense that the actress uses social media/an app to keep in touch, considering Emma Watson recently gave out advice via an iPad. Girl definitely seems somewhat tech-savvy (though perhaps not AS proficient as she is with a wand *wink*).

Matthew Lewis and fiancee

The app seemed to do the trick: Not only did Lewis take Watson up on her offer, walking the carpet with his fianc茅e Angela Jones, but Tom Felton (AKA Draco Malfoy) was in attendance as well, despite reportedly skipping carpet fanfare.

Lewis, for one, had nothing but awesome things to say about his former castmate. 鈥淧eople try to pigeonhole young actresses and tell them what they should and shouldn鈥檛 be doing. Emma was always very keen to do whatever the hell she wanted to do, and I think she鈥檚 done that.鈥

He added, 鈥淪he鈥檚 hoping to use her experiences to try and help people, and I think that鈥檚 absolutely fantastic. I think that she鈥檒l do it with Belle 鈥 Belle won鈥檛 be a damsel in distress.鈥

With an app like that, clearly not!

Does it surprise you that Emma Watson still keeps in touch with the Harry Potter gang? Let us know @BritandCo!
