When you've only just started shooting on your latest film, rustling up something interesting to show people can be a daunting challenge. But it was one that Sami Raimi was willing to tackle for a presentation of Oz The Great And Powerful at this weekend’s D23 Expo.

But he also provided an early glimpse of what the film might look like, with concept art and rough footage from the first day’s shooting interspersed with sound bites from the cast, including James Franco, Mila Kunis, Michelle Williams, Zach Braff and Rachel Weisz.

As Raimi mentioned in the video, the aim for the film is to take the descriptions of Oz used by L Frank Baum in The Wonderful Wizard of Oz and bring them to life with all the technological tricks of modern filmmaking. So we were treated to lush imagery of rolling hills, mountains that resembled elephant heads and scary forests, all boasting the iconic yellow brick road.
