Among the newest members of the Screen Actors Guild is Daniel A. Thomas, who calls himself a “New York lawyer first” despite a growing list of Hollywood pals and paying projects.

Thomas, a plaintiffs medical malpractice solo practitioner in Manhattan and the son of Queens Supreme Court Justice Charles J. Thomas, had fully expected to remain behind the camera as a producer in his second career. But he was obliged to join the performers’ union on the occasion of his latest movie venture, which wound up providing him the fluke opportunity of portraying, of all things, a lawyer.
