When they first met in 2000, Franco impressed Raimi as a great actor but a little conceited and selfish. When they made Spider-Man 2, Raimi found Franco to be a better listener and was more giving. By the time the third Spider-Man movie was made, Raimi saw him developing a soul and becoming a more mature man.

"What is interesting for me is to watch the whole progression of Franco to a much nicer, opener and more mature professional actor," he says. "That's kind of what the Wizard goes through in our movie. If James could recognize what he has been through in life, how he has changed, and who he is now, he can sympathize and put it into the performance."

The film is Raimi's first foray into 3D technology. To better introduce the audience to the fantastic world of Oz and give them a sense of dimensionality, he designs a special 18-minute long opening for the film.

The story begins in Kansas in the year 1905. It's presented in black-and-white. The 3D is dialed down. The soundtrack will be mono.

When the protagonist gets to the Land of Oz, the screen opens up to a widescreen format. The sound will transit from mono into the full 7.1 sound, bringing the choir up on the track, and the image goes to full color and the 3D is dialed up.

"I hope that together these effects will be a powerful experience for the audience," Raimi says.

The making of the approximately $200 million movie does not mean he will only focus on blockbusters. He and his brother are now working on the script of The Evil Dead 4.

"I like doing both of them very much," he says. "On the big budget movies, it's very exciting to be surrounded by all the best artists in the field. You can use the latest equipment and techniques, try different ways of filming, but it's a bit hands-off.

"When you make independent little movies, you have to use what's available, you don't always work with the very best people, but you are not that divorced from the audience, you feel you are right in the middle of them."
