Q: Which was the earliest feature-length animated film? A: The earliest feature-length animated film is "Snow White and the Seven Dwarfs," produced by Walt Disney Productions and released in 1937. It was the first full-length cel-animated feature in motion picture history and is considered a significant milestone in the art of animation. Q: Are you sure? A: Apologies for the confusion in my previous response. Upon further reflection, I realize I made an error. The earliest feature-length animated film is "El Apóstol" (The Apostle), an Argentine film directed by Quirino Cristiani. It was released in 1917 and is considered the first full-length animated feature film in history. Unfortunately, all known copies of "El Apóstol" were lost in a fire, and no prints of the film are known to exist today. Full Conversations
