In 1928, "Plane Crazy" became the first entry into the Mickey Mouse series; however, it was not released because of a poor reaction from test screenings and failed to gain a distributor. The second Mickey Mouse cartoon "The Gallopin' Gaucho" also failed to gain the attention of the audience and a distributor. Disney knew what was missing: sound. Sound film had been captivating audiences since 1927 with "The Jazz Singer" and Walt decided that the next cartoon "Steamboat Willie" would have sound. "Steamboat Willie" was not the first sound cartoon, Max and Dave Fleischer had produced "Song Car-Tunes" since 1926. However, they failed to keep the sound synchronized with the animation and the main focus of the cartoons were the bouncing ball sing-a-longs. The "Song Car-Tunes" were not a success and some staff members doubted whether a cartoon with sound would be successful. So Disney arranged a special preview screening with the music and sound effects being played live behind stage through a microphone. The "Steamboat Willie" test screening was a success and managed to gain a distributor, "Celebrity Pictures" chief Pat Powers. However, the first attempt to synchronize the sound with the animation was a disaster with the timing being all wrong. In order to finance the second recording, Walt sold his car. This time he used a click track to keep his musicians on the beat (Disney later learned that it was easier to record the dialogue, music and sound effects first and animate to the sound). Little more than a month before "Steamboat Willie'"s premiere, Paul Terry released his sound cartoon "Dinner Time"; however it was not a financial success and Walt Disney described it as "a bunch of racket".
