20Saved: Han Shoots First
Regardless of Lucas’s intention, the original cut from 1977 shows Han shooting first, and it’s a good decision.
Whether or not Han shot first has got to be one of the biggest controversies surrounding the Special Edition released in 1997. The original version had Han shooting first, but the Special Edition had Greedo initiating the conflict. However, apparently George Lucas had always intended for Greedo to shoot first.
Speaking about the change in the Special Edition, Lucas explains that Greedo shooting first better fits his true vision, as Han was never meant to be a cold-blooded criminal.
It establishes Han as something of a rogue and anti-hero, allowing him to have a complete arc as he changes his mind about his role in the Rebellion thanks to his relationship with Luke and Leia.
