Beymer left Hollywood in 1963 to try his hand at directing experimental films and documentaries and lensing TV features. He became involved in the 60s struggles for civil rights and directed and photographed the documentary, "A Regular Bouquet" (1964), which later aired on the PBS series, "Eyes on the Prize". He didn't return to acting (with the exception of starring in his own directed and produced independent film, "Innerview" 1973) until the 1980s with the thriller, "Cross Country" (1983). Beymer also made a TV appearance on "Paper Dolls" (ABC, 1984) and in the exploitation horror film, "Silent Night Deadly Night III: Better Watch Out" (1989).

Beymer scored a comeback of sorts in TV's "Twin Peaks" (ABC, 1990-91), as the wildly villainous entrepreneur, Ben Horne, giving a looser, funkier performance than any in his earlier career. In films, Beymer made brief appearances in the sequel "My Girl 2" and the erotic thriller "Under Investigation" (both 1994).
