Greedo shot first. Greedo shot Han and missed (as seen in the gif), then Han quickly to defend himself shoots back at Greedo.
In the original take, Han was the only one to shoot. As in the edits made in the future, Han looked to shot second. If you are talking about first film with no CGI/Future edits, then Han shot first. If you're talking about the edited film, then Greedo shot first.
I've seen the old star wars movies without the special effects and the editing. So I can 100% say that Han shot first
For the people who haven't seen the new movie(I'm sorry) I'll put this in a spoiler ;p Spoiler: ayy lmao Han is dead, so it doesn't matter. <3 ;3 oh, and Chewie got shot! ;0
Han shot first, anything George Lucas added in the "special editions" is completely stupid. Ruining the original trilogy with bad CGI, especially in the first Star Wars.
Yeah, but it was called the "1997 special edition", so I call it that. Not to mention the terrible Jabba. Literally. I don't want to mention that monstrosity of bad CGI. (Shudder)
