It's unquestionably the most infamous no-hitter in baseball history — the one that Pittsburgh Pirates Doc Ellis pitched while high on LSD on June 12, 1970.

Learn about this unique athletic feat and more about the life of Ellis in the new documentary film, No No: A Dockumentary. Catch a sneak preview of the film at 7 p.m. Tue., Aug. 26, at the Harris Theater. Following the screening, there will be a Q&A with director Jeffrey Radic and Dock's agent, Tom Reich.

The film returns for a week-long engagement on Sept. 5, at Regent Square.
