Neil Patrick Harris will visit the Alamo Drafthouse Sloan’s Lake location on Thursday, Sept. 27 for a book talk, movie screening and “meet-and-greet opportunity,” the Drafthouse announced today. The “How I Met Your Mother” co-star and Tony-award winning stage actor, known as much for his rabid online fan base as his activism and agreeable media presence, will read from new book “The Magic Misfits: The Second Story” before screening a yet-to-be determined film. Tickets for the event, which is presented by the Tattered Cover and runs from 7 to 10 p.m.
