Focus Features Intl. has scooped up overseas sales and distrib rights to writer-helmer Michel Gondry’s upcoming “Be Kind Rewind” starring Jack Black. Pics stars Black as a man who becomes accidentally magnetized while trying to sabotage a power plant. His magnetic field erases all the tapes in the video store where his best friend works. To save the store, the duo re-enact and re-film every movie that its single loyal customer, an elderly woman, rents.
