Actor Martin Sheen, who turns 79 today, pictured on the set of 'Apocalypse Now' with Francis Ford Coppola behind the camera filming Frederic Forrest.⁠ Sheen spent his 36th birthday on location, shooting the opening sequence in a Saigon hotel room. He was said to be completely inebriated. ⁠ Before the film wrapped after a notorious production run, Sheen had suffered a minor heart attack.⁠ Faring better today and with a remarkable body of work to his name, Sheen is also father to the Sheen and Estevez acting dynasty.⁠ 📷: Steve Schapiro/Corbis via Getty Images | 1979⁠ schapirophoto | gettyarchive⁠ ⁠ #martinsheen #steveschapiro #apocalypsenow #francisfordcoppola #1979 #fredericforrest #onset #onlocation #heartofdarkness #onsetphotography #thehorrorthehorror #thenewhollywood #hollywoodhistory #cinemahistory #archivephoto #photoarchive #historyphoto #historyinphotos #onthisdayinhistory #gettyarchive ⁠ ⁠
