'Oz: The Great and Powerful' went all out for its red carpet premiere on Wednesday with a yellow brick road and even a recreation of James Franco's hot air balloon from the film. Though the rest of us have to wait until March 8 to see this in theaters, a new sneak peek has hit the web thanks to one of the Wicked Witches from the movie, Rachel Weisz.

The Golden Globe- and Oscar-winning starlet came on 'Jimmy Kimmel Live' to promote her latest gig, that of the witch Evanora in Sam Raimi's 'Oz: The Great and Powerful,' and she brought with her the first clip from the film.

In the new footage, featuring Weisz and her on-screen sister Theodora (Mila Kunis), it seems Disney is no longer trying to cover up which of these sorceresses will become the infamous Wicked Witch of the West. They already let her true identity slip a while back, so now the real excitement will come from seeing her transformation happen on screen.

Watch the first 'Oz: The Great and Powerful' clip below, courtesy of 'Jimmy Kimmel Live,' and be sure to check out the film when it hits theaters March 8.

UPDATE -- 2/21/13: Yahoo Movies released a longer version of the clip from 'Oz, The Great and Powerful.' Check it out below:
