The roles and responsibilities of a talent manager vary slightly from industry to industry, as do the commissions to which the manager is entitled. For example, a music manager's duties differ from those managers who advise actors, writers, or directors. A manager can also help artists find an agent, or help them decide when to leave their current agent and identify whom to select as a new agent. Talent agents have the authority to make deals for their clients while managers usually can only informally establish connections with producers and studios but do not have the ability to negotiate contracts.
