The Toonerville Trolley films were the most successful and popular films ever made at the Betzwood studio. Based on the famed newspaper cartoons of Fontaine Fox, they were written by Fox himself. Only seven of the original seventeen two-reel comedies survive today. Copies of four have been added to the Betzwood Archive and efforts continue to raise money to save the rest before they are destroyed by nitrate decomposition.
