Only made about 60 pictures. Only. I guess he didn't have the pipes for the new medium.

With the advent of sound in the motion picture industry, Hines career went into decline. During the 1930s, he would appear in only six films, all in smaller, supporting roles. In 1938 he would have his last significant role, that of Parsons in Too Hot to Handle, which starred Clark Gable, Myrna Loy and Walter Pidgeon. He would appear in only one more film, 1946's Magnificent Doll, starring Ginger Rogers and David Niven, in which he would have a bit part.

Wonder if anyone on the cast or crew went out of thier way to welcome him back. Or whether his coming and going wasn't noted at all, since it implied what could happen to any of them.
