Harry Shearer, of “Simpsons” and “Spinal Tap” fame, will introduce his documentary “The Big Uneasy” in person on May 14 at Studio 35, 3055 Indianola Ave. He’ll speak briefly before and after two screenings of the film, at 7 and 9:15 p.m. Tickets are just $7.50 and are available through Studio 35’s website.

Shearer, who calls himself a New Orleanian, says his film is not a Hurricane Katrina film, but a film about New Orleans and the bureaucratic and engineering flaws that led to devastating flooding in the wake of Katrina.

Shearer, who’s known as the voice of Ned Flanders, Smithers and other key characters on “The Simpsons,” as well as for his portrayal of bassist Derek Smalls in “Spinal Tap,” has been sounding off about media and government response to Hurricane Katrina for years.

The film is making the rounds at theaters and film festivals, where it has won several awards.
