I thought I saw someone post about this on JD somewhere, but couldn't find a thread.
If you haven't checked out the Light and Magic documentaries on Disney+ you should give it look. Its fairly comprehensive, but there are some really cool things in there that I hadn't seen before. It was great to watch while on the treadmill.
It spends a lot of time on the early years of ILM and the people that drove the OT special effects. It moves a lot more quickly from '83 until now.
One big thing that I didn't realize is that John Knoll (from ILM) was one of the co-creators of Photoshop with his brother. He was trying to figure out how to do some digital editing and morphing and essentially created the original Photoshop before it was sold off to Adobe. I checked, and his and his brother's name are still near the top of the list for credits when Photoshop is loading. Very cool.
