I'm not sure why the address is coming up as Harvard U -- this is the Harvard Film Archive, located within the university but open to the public (admission fees are around $10, but you can become a member.)
Wonderful selection of films. This can be one's film school. Often undergrad film courses will orchestrate showings of a particular director -- Bresson, or Antonioni or Bergman.
Famously designed movie theatre. Very hip place.
One of the most enjoyable movie theatres in Boston, if not the country, with an incredibly fine selection of films selected by the curatorial staff.
Highly highly recommended.
