Trash Night Video: โMunchie Strikes Backโ from 7:30 to 10:30 p.m. at The Brattle Theatre, 40 Brattle St., Harvard Square. Tickets are $8. This monthly film event lovingly selects and screens cinematic trash, and โMunchie Strikes Backโ is that โย an inept 1994 kidโs film that these days weโd suspect was written by AI, from the teen romance to the sports redemption story to the momโs sleazy boss (mom is Lesley-Anne Down, eliciting sympathy for the path she traveled since โUpstairs, Downstairsโ) with an unconvincing and supposedly wacky imp character all purรฉed into a film in which โa goodly portion of the appealโ is spotting how many times the cinematographers allowed the board Munchie is nailed to into the shot. Information is here.
