Brainstorm. On a sheet of paper, write down every production you've ever been a part of as an actor. Don't be afraid if you think your acting credits are small; everybody starts somewhere. Whether it was a movie, TV show, a local commercial or community theater, it all counts, so be sure to list it.
Create a header. The top of the page should include your name, preferably in a large bold font, followed by your contact information, which should be in a smaller font. Don't be bashful. List as many ways for people to get in contact with you as possible. Home address, home phone, cell phone and email.
Separate your resume into sections. Your biggest and most notable acting work should always be listed first. For most cases, this would be movies, followed by TV, then theater, and finally commercials. Fill these sections in with the appropriate credits.
Tell about yourself. In the last section of the page, list personal statistics. For instance, list your height, weight, eye color and hair color. Then create a special skills section that allows you to add any additional information helpful to a casting director or agent. If you are particularly good at horseback riding, or playing volleyball, be sure to write it down. List anything you can think of that might appear in a movie, TV show or commercial that you honestly do well and could perform on camera. Who knows? That extra edge might help you get the job!
Revise and review. There's nothing more annoying to a casting director or agent than someone who has too many credits. If you're in your twenties and still listing a part you played in the town play from when you were four, it might be time to remove that item. The bottom line is: use your judgment and keep your resume current.
