An inspired idea for a film series if ever there was one — the SF Maritime National Historical Park is showing nautically themed films onboard the ferryboat Eureka at Hyde Street Pier. They began last month with 2003’s Pirates of the Carribean: The Curse of the Black Pearl, and they’re picking up Thurs/15 with Lifeboat (1944), Alfred Hitchcock’s production of a John Steinbeck story, starring Tallulah Bankhead. Next month, step aboard the Eureka for Jaws (1975) — that is, if they don’t end up needing a bigger boat. Teasers and show info after the jump:
