Karl Friedrich Anton Hermann Charles Regnier (22 July 1914 – 13 September 2001) was a German actor, director, radio actor and translator. (Some sources inaccurately place Regnier's birth year as 1915.) He appeared in more than 135 films between 1949 and 2000. In the 1950s and 1960s, he was one of the busiest German theater and film actors. His idiosyncratic, decidedly intellectual style and his sometimes slightly mocking acting, distant demeanor became his trademark and made him a much sought-after character actor.
