Have professional photos taken for your portfolio. At a very minimum, you should have at least 20 black and white glossy headshots on 8-by-10 inch paper. Tape or lightly rubber cement your resume to the back of each photograph.
Hire an agent to assist in scouting new roles for you. This doesn't mean, however, that you shouldn't be keeping your own eyes and ears open for opportunities.
Enroll in film acting classes. This will not only enable you to keep honing your craft but also to network with fellow actors who will have their own feelers out for audition opportunities. In addition, it's likely that information for upcoming auditions will be disseminated in class by your instructor or posted on job bulletin boards at the school or studio where you are studying.
Subscribe to online casting services and notice boards. These will allow you to receive daily casting updates, advice columns on audition techniques, insider scoops on new productions in the works, and exchange rants and raves with your fellow community of actors. For additional fees, some of these websites will also allow you to post your headshots and resumes as well as upload mini film clips of your work (see Resources below).
Register as an actor at your state's film commission. Because so many productions are shot on location, these commissions were formed to assist directors and producers in renting properties for their film shoots, coordinating street closures, and utilizing local talent and tech crews as a way to keep down expenses.
Read film trade magazines such as "The Hollywood Reporter" and "Variety," especially if you live in Los Angeles or New York. These will keep you abreast of the latest entertainment news, including casting notices for shows that are going into production.
Volunteer! Whether it's to be part of a background crowd scene or the star of a quirky student film, it all adds up to acting credits and more experience. And who knows, you might catch the eye of the director for an upcoming project that will give you more pay and prestige.
