The sweet-tempered Michel Gondry works well with sharp-edged material (Eternal Sunshine of the Spotless Mind), but his projects as a solo writer-director have been soft and surreal celebrations of innocence that threaten to drift off into whimsy (The Science of Sleep and now this feature). Danny Glover entrusts his run-down video shop in Passaic to clueless assistants Jack Black and Mos Def, who accidentally erase all the videos and decide to shoot their own low-rent versions of popular hits. Their project is a great success with customers, but the studios object and Glover gets an eviction notice. This anachronistic tale goes beyond Capracorn to evoke Depression-era fare like One Hundred Men and a Girl in which the charm is overtaken by mush. One wants to protect this, but it’s hard not to gag on the cuteness. With Melonie Diaz and Mia Farrow. PG-13, 101 min.
