Full vegetarian dinner menu available, plus discounts on craft beer and organic wine during the film. 8 p.m. showtime, with rare Elvis Costello items raffled off beforehand.

The Psychotronic Film Society’s ongoing Wednesday night series of underappreciated or downright obscure feature programming from around the globe continues Aug. 22 at The Sentient Bean with a salute to the esteemed, genre-crossing English singer-songwriter-actor Elvis Costello, on the occasion of his 64th birthday, which takes place just a few days later. Costello, who first came to international prominence in the late 1970s as one of the most idiosyncratic, aggressive (and undeniably Dylan-esque) tunesmiths to emerge from the punk and new-wave music scenes has since become an elder statesman of intelligent, nuanced songwriting and a legendarily magnetic and aggressive band frontman and solo act. He has also dabbled in acting on both the small and big screens and served as a well-regarded TV talk show host.

The exact title of this feature-length Costello film (which is rarely seen in public) remains a closely guarded secret until showtime. Will it be a musical concert movie, a dramatic film in which Costello plays a key role, a documentary on the musician himself, or something else entirely? Fans and curious viewers are encouraged to take a chance, buy a ticket and be pleasantly surprised.
