An amiable, partially contrived documentary by Mika Kaurismaki (1994) in which Jim Jarmusch joins Sam Fuller as Fuller returns to a Brazilian rain forest where 40 years earlier he scouted locations and shot 16-millimeter footage for a Hollywood adventure story that was never made. What keeps this fun and watchable are Fuller and Jarmusch holding forth for the camera and each other, but the settings and the Karaja Indians they visit hold plenty of fascination as well. Winner of the international critics’ award at the Berlin film festival. Music Box, Saturday and Sunday, April 1 and 2.
