Find out where auditions are being held. The best way to do this is to sign with an agent. An acting agent will have the most current and accurate information about Disney roles available. With Disney Channel roles in such high demand, an unknown actor with a qualified agent will have a better chance than someone who is trying to snag an audition on their own. Locate an agent by searching your local yellow pages or an online community of classified ads such as Craigslist.
Visit the corporate section of Disney Channel's website. Often, Disney will list information about open casting calls, auditions, or extra opportunities. This is an excellent resource for actors with no agent. While you won't be as well informed as you would be with an agent, regularly checking the Disney site will at least give you a leg up on Disney acting opportunities in your area.
Don't disregard other opportunities Disney has to offer. Some Disney Channel stars began their careers with Disney in other facets of the corporation. Consider working in the entertainment department of one of Disney's theme parks or on their cruise ship. You never know the connections you could make that could help you down the road as you try to audition for a Disney channel movie. Plus, it never hurts to already have Disney on your resume as you enter your audition.
Send a resume, photo, and video of yourself to Disney. While this is a long shot, it has worked in the past. On your resume include any past acting work you have done including commercials, local theater and school plays. Photos should be professionally taken color pictures showcasing your face. If you make a video, be sure you are the only one featured on the tape. If you are reading a scene, have the person reading opposite of you out of the camera's sight.
