As much as I am moved by the Passion of Christ and the suffering that He endured, in my opinion the greater story is of Him overcoming death and getting His disciples to believe in the impossible. While movies have been made of His crucifixion, I feel that the greater movie would start at that point and follow His disciples on their path from despair and betrayal to their understanding and then preaching of Christ's message. What is often the denouement of movie versions of Christ's life is actually the most important part.
Christ's resurrection is the fulfillment of prophecies and covenants. It shows that God is true to His word. It demonstrates that God can take the most awful events and turn them into something glorious. It proves that we are right to place our hope in Him.
