What is the difference between an agency and a management?

Talent agents for actors come in two main types, theatrical (Television and Film) and commercial ( for commercials). There are also dance, print, and voice-over agents who specialize in these fields, and signing with one of these agents can be a great way for actors with these other skills to cross over into one of the other areas. Being with the same agency for everything is called being "signed across the board," but many actors prefer to have separate agents for different types of work, become some agencies might be strong commercially, but not as strong theatrically, or vice versa. Agents get information about auditions for roles, either directly from casting directors and producers calling them asking for client submissions, or from a fax/email service called "the breakdowns," a daily list of roles being cast, sent only to agents and managers, although there is a black market for this information within the acting community and many actors without representation self-submit for available roles, which some casting people don't mind, others hate, and the owner of Breakdown Services abhors. Remember actors--your agents work for you, but they only get 10% of what you make, so that means you need to do 90% of the work--especially when you are getting started. That means always be professional, know your craft, don't shy away from networking and letting CD, producers and directors know about your accomplishments & upcoming appearances by sending out postcards, know your type and how you fit into the current market, and above all, make sure you and your agent are on the same page about what kinds of parts you will be submitted for.

A manager is someone who manages your career after you have established yourself in the business. Managers generally get 15% of your gross income from acting jobs. There are many unscrupulous "managers" out there claiming to have the ability to make someone a star. The truth is, a manager can recommend photographers, classes & workshops, resume printing services, etc. But this information is available for free, and is certainly not worth paying 15% of your income.
