Mr. Smith Goes to Washington
Carpenter announced for Al Jolson and Edgar Bergen as well. By virtue of his extensive announcing career, he wound up with uncredited roles in well-known movies, including "Mr. Smith Goes to Washington" and "Susan Slept Here". He was also the narrator for producer Jerry Fairbanks' theatrical short-subject series "Unusual Occupations", released by Paramount Pictures from 1938 through 1948.
