Mark Muir works with actors, authors, writers, producers, directors, crew members, and multi-hyphenates to negotiate their business deals in the entertainment industry.

Mark brings a unique perspective to transactional entertainment law, informed by his experience working in television production, as an in-house attorney for a major talent agency, and now advising clients as an attorney at a leading entertainment law firm. After graduating from UCLA, he started out working in the entertainment industry and learned the fundamentals of production as a field producer in reality television. Mark then continued his education at UC Hastings, with the goal of learning the law as it applies to the entertainment industry.

After earning his law degree, Mark returned to Los Angeles and went to work as an in-house attorney for one of the top talent agencies in the industry, drafting and negotiating hundreds of agreements for the agency’s acclaimed clientele with all of the major and mini-major studios, networks, production companies, and publishing houses, as well as with independents of all sizes. From his rare combination of experience producing television and working as an attorney at the high-volume agency, Mark had gained both a practical understanding of the day-to-day of industry professionals and the experience and knowledge to protect the real-world needs and wants of his clients.
