When Elliott Gould became a full-fledged movie star in 1970 with the release of “M*A*S*H,” Time magazine christened him “Star for an Uptight Age.” Now the Brooklyn Academy of Music (BAM) is hosting a retrospective of Gould’s films; it’s called "Elliott Gould: Star for an Uptight Age." It runs through August 21 and features screenings of “Little Murders” (1971), “The Long Goodbye” (1973), “California Split” (1974), and many others.
