Have "head shots" taken (if you're trying to be an actor or actress). Head shots are professional photographs of yourself to send out to casting agents with your proper resume printed on the back. The higher the quality of your head shots, the more likely you are to stick out in the mind of a casting agent or producer who happens to see your resume.
Focus on your technical experience, not your education. Landing a job in the entertainment industry relies heavily on first-hand experience and not which college or university you attended. If you're running out of space on your resume, feel free to include this information. However, if it comes down to putting your education information into the resume or putting in one last example of technical experience, leave off education and focus on technical experience.
Gear the information on your resume toward the type of job you're trying to attain. For example, if you're trying to find a job as a camera operator, leave off all the acting experience you have and instead focus on instances where you've operated a camera. If you're trying to be a production assistant, focus on all the times you performed that job as opposed to jobs in other departments.
