April 7 - Adam West
April 14 - Sheree North
April 28 - Clint Eastwood
After identifying those three, I saw the pattern and correctly identified Ann Sothern.
April 21 - Ann Sothern
I guess I'm excused for not recognizing the actresses. Looking at her filmography, I can only recall two of Sheree North's films - Charley Varrick and The Shootist. I can only recall one film with Ann Sothern - A Letter to Three Wives.
The clues are directional - North, South, East & West. I believe the clues are pointing us to Earth Day (April 22). By the way, the calendar states "TBA" for April 22 but the website states the Castro will be closed that day. The films for April 15 have not been posted.
A second possible solution is the 2014 San Francisco International Film Festival with emphasis on "International" as in the four corners of the globe The festival lineup was announced on April 1 and the festival begins on April 24 at the Castro so this gives it some credence.
