Will Smith will play the Genie in Guy Ritchie's Aladdin remake

Disney has announced that Will Smith will play the Genie in the live action remake of Aladdin.

It's one of many new revelations the studio has made about some of its upcoming films.

Lots of secret footage was also released, from upcoming films including The Lion King, Avengers: Infinity War film and Star Wars: The Last Jedi.

The updates came from Disney's D23 Expo, a fan event in southern California.

After months of speculation, Disney confirmed Will Smith will take the role famously voiced by Robin Williams in the 1992 cartoon version of Aladdin.

The role of Aladdin will be played by Egyptian-Canadian actor Mena Massoud, who stars in the new Amazon series Jack Ryan.

English actress Naomi Scott, best known for playing Pink Ranger in the Power Rangers movie, will take the role of Jasmine.

Mena Massoud is not yet very well-known in the UK.

While Star Wars fans didn't get a new trailer for episode eight, they were treated to a behind-the-scenes teaser.

"Some of the stuff that happens - people are going to be like, 'Oh my God,'" says Daisy Ridley, who plays Rey.

The clip also features the late Carrie Fisher, who plays Leia for the final time when the film comes out in December this year.
