Charlie Sheen, who shared the screen with Stanton on Red Dawn and Two and a Half Men, also expressed his sadness.
"Harry Dean Stanton, brilliantly and effortlessly, played my father twice and my Sage once. All the while, in between and often, he played with our collective hearts and imaginations, in methods unworthy of this scribe's deciphering," Sheen wrote in a statement given to ET. "From Cool Hand Luke to Alien, his on-screen poetry reminded the rest of us, to seriously consider a day job. His valiant cry to 'Avenge me' from the internment camp in Red Dawn, will forever echo in the pantheon of my greatest memories. Rest in peace, good sir."
David Lynch, who worked with Stanton on various Twin Peaks projects, released a statement on Showtime's official Twitter page, calling the late actor "a great human being."
