James Franco, Mila Kunis, Michelle Williams and Rachel Weisz are the famous faces of the new Oz prequel, but a behind-the-scenes video shines the spotlight on the crew members who played a key part in making the movie’s magic happen.

In this clip, Oscar-winning production designer Robert Stromberg (Avatar, Alice in Wonderland) explains how he helped create the whimsical world of Oz, while costume designer Gary Jones describes the process of outfitting the cast and the “joy of working in a land of sheer fantasy.” Special makeup effects artist Howard Berger and makeup department head Vivian Baker also chime in on creating the “big, green, scary witch,” and designing the look of hundreds of background characters.

“Viewers will experience a fantastical world and amazing story,” Franco promises.
