Names are as UCDP writes them, with two labels that the site writes. UCDP does not identify some actors: the site writes "Actor not identified by UCDP" for each of them. UCDP names some groups for a person: the site writes "Group named for a person (name not shown)" for each of them. A line with a label can hold more than one actor.
