Summarily, for Christians, the origin of Easter is simply the crucifixion and resurrection of Jesus Christ. Sadly, traditions that have nothing to do with Jesus, such as the Easter Bunny and Easter Eggs have become very popular. In fact, two animated feature films have been commissioned about the Easter Bunny. One such films tells the story of how the Easter Bunny is injured by a reckless driver, forcing the driver to take up the role of Bunny in order to "save" Easter. How ironic.
And sad.
