In "Dear America: Letters Home from Vietnam," originally broadcast on HBO in 1988, an all-star cast reads from the actual personal letters written home by the men and women who served overseas during the war. Featuring the voices of Robert DeNiro, MartinSheen, Sean Penn, Willem Dafoe, Elizabeth McGovern, Harvey Keitel, John Heard, Kathleen Turner, Robert Downey, Jr. and many others. Period music includes selections from Creedence Clearwater Revival and the Doors. Combining photographs and home-movie footage shot by the servicemen and women themselves, it's a vivid recreation of the time when America lost its innocence.
