Reggie Nalder (born Alfred Natzler; 4 September 1907 – 19 November 1991) was a prolific Austrian film and television character actor from the late 1940s to the early 1990s.
Nalder is perhaps best remembered for his roles as an assassin in Alfred Hitchcock's 1956 remake of The Man Who Knew Too Much, the vampire Kurt Barlow in the 1979 TV adaptation of the Stephen King novel Salem's Lot, and the Andorian ambassador Shras in the Star Trek episode "Journey to Babel".
Nalder appeared, at the request of star Frank Sinatra, in a brief, uncredited role as a communist spymaster named Dmitri in John Frankenheimer's 1962 film The Manchurian Candidate.
"[5] Nalder's television work also included episodes of the series 77 Sunset Strip, It Takes A Thief, Surfside Six, Boris Karloff's Thriller ("The Terror In Teakwood" and "The Return Of Andrew Bentley"), McCloud and I Spy.
Nalder was also credited as "Detlef Van Berg" in the X rated films Dracula Sucks (1978) and Blue Ice (1985), but performed in no scenes of a pornographic nature.
