Daffy first appeared in 'Porky's Duck Hunt', released on April 17, 1937. The cartoon was directed by Tex Avery and animated by Bob Clampett. 'Porky's Duck Hunt' is a standard hunter/prey pairing for which Leon Schlesinger's studio was famous, but Daffy (barely more than an unnamed bit player in this short) was something new to moviegoers: an assertive, completely unrestrained, combative protagonist.
Clampett later recalled:
"At that time, audiences weren't accustomed to seeing a cartoon character do these things. And so, when it hit the theaters it was an explosion. People would leave the theaters talking about this daffy duck."
