You can join a casting network free of charge, so long as you have an agent. Most casting networks will charge you a fee annually to feature your profile if you do not have a casting agent. They often offer different levels of membership, with basic membership setting you back around $25 per year. You will need to have an up-to-date resume and headshot to upload your profile. Your agent should be able to sort out profiles for you to maximize responses. There are several casting networks available that are suited to a variety of needs. For example, there are worldwide databases for casting calls that are used by major production companies and their casting panels. By having your profile featured on their platform, you are more likely to be approached for work opportunities than if you were just applying yourself locally. International clients can contact you or your agent this way as you may fill a niche that they have not been able to find an actor for closer to home. You are also able to specify the type of acting work that you are interested in on your profile, along with your unique set of skills, talent, and previous roles.
