"The Master"

In Paul Thomas Anderson's "The Master" (Weinstein Co., 2012) we get a scene in a theatre (supposedly in Lynn, Massachusetts) with Joaquin Phoenix and his girlfriend Doris in front of the lobby's crystal fountain. We're at the Los Angeles Theatre, 615 S. Broadway.

Later in "The Master" we're passing out flyers in front of the boxoffice of the Los Angeles for an event set in Phoenix.

Another shot in front. 

And there's a great little scene later in up in the second balcony where Phoenix, presumably the theatre's manager, is alone watching a Casper cartoon.

He gets a phone call and an usher brings a telephone to his seat. It's the Master (Philip Seymour Hoffman) calling him back. See the many pages about the Los Angeles Theatre on the Los Angeles Theatres site for a history of the building and hundreds of photos.
