No one film can fully capture the life story of a figure as monumental as Roberto Clemente. But “Clemente,” a new documentary from writer/director David Altrogge, comes awfully close. A half-dozen or more members of Clemente’s family are present, including his wife, Vera, in interviews recorded before her 2019 death. The film, which plays locally this weekend before being broadcast on the History Channel Sept. 23, will receive a grand rollout in Clemente’s adopted home. The following day, Clemente Museum founder Duane Rieder will introduce the film at Sewickley’s Lindsay Theater.
