His movie debut was in the film "The Magnificent Lie" (1931) with Ralph Bellamy and Charles Boyer, but Kent Taylor was not credited in this movie.
In 1942 he starred as Doc Holiday in "Tombstone, the town too tough to die" along with Richar Dix who played the Wyatt Earp part. His portrayal of Holiday was remarkable.
The Rough Riders was his other important TV show, it was about the adventures of three Union men in the west, he played Captain Jim Flagg.
Boston Blackie in 1951 was his best performance, curiously his last films were very bad horror flics just as Basil Rathbone, the actor who best portrayed another famous sleuth, Sherlock Holmes.
He was a guest actor in many TV shows such as Bat Masterson, Zorro, The Rifleman, Hawaiian Eye and Land of the Giants
