Question: Who plays Deep Throat? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: All the President's Men Context: On the early morning hours of June 19, 1972, a security guard (Frank Wills, playing himself) at the Watergate complex finds a door kept unlocked with tape. The police arrive where they find and arrest five burglars in the Democratic National Committee headquarters office within the complex.
