You need to get permission from the copyright owner to make a copy of a motion picture. Write a letter to Disney's legal department telling them exactly what you want to do. Mail the letter registered mail to prove that they have received it, because the only exemption is if you do not receive a response in a reasonably time, as defined by copyright law, you can make a copy. The only other exemption has been for libraries if they are unable to purchase the motion picture for a reasonable price.
