premise: Walter Clarence Taylor Jr. (February 26, 1907 – October 3, 1994), known as Dub Taylor, was an American character actor who from the 1940s into the 1990s worked extensively in films and on television, often in Westerns but in comedies. He was the father of actor Buck Taylor, who played the character Newly O'Brien on "Gunsmoke".
hypothesis: Dub Taylor was acting in movies right up until the year he died, which was 1994.
reason: We know he acted into the 1990's but don't know exactly when he last acted. The system didn't figure out that he might or might not have acted in 1994 prior to his death.
