Quoted from DakotaMike:Awesome looking homebrew. Very cool. Also, in about 4 years "Steamboat Willie" will enter the public domain, and then anyone and everyone can use anything from that short film anyway they want. Basically. Hopefully, you'll be able to take it to some more shows when they start having them again.
Unless they get it extended again. Also, you'd have to pull the assets from an ORIGINAL print of the film, not any of the digit restorations that you'd probably be able to source today - they'd sue based on the restoration copyright date instead. Also, pretty sure the character of mickey mouse in general is trademarked.
