Baker's first film, and one of his best, was COURAGE OF THE WEST released in 1937. The next year he made a total of nine features and was listed in the Top Ten Moneymaking Western Star poll. In his pictures he rode a beautiful paint horse called Apache. One of his movies for Universal, LAST STAND – 1938 was the basis of a comic book (see below).
Shortly after making his twelfth feature (PHANTOM STAGE), Universal hired Johnny Mack Brown. The studio then formed a trio of Brown, Baker and Fuzzy Knight, and their first movie was DESPERATE TRAILS (1939). Baker made six features with Brown, but his role was never equal to Brown's. In fact, in OKLAHOMA RAIDERS, Baker was killed off about half way through the picture. Baker's career then went downhill and he got out of the movies.
