The F65 was never 8K. It used a very specific sub-pixel pattern that enabled full color depth at 4K, similar to how an 8K sensor would allow the same.
He's shot tons of commercials on Red...
You do realized that Lacie don't actually make hard-drives, right? Their hard drives are no worse or better than anyone else's.
Their rugged builds do exactly what they're meant to, they add shock-absorbing material around the drive, so that if you were to drop it, the drive itself doesn't the grunt of the impact. That does in no way mean that the drives themselves are any less fragile.
Looking at their bigger drives, Lacie are on top of things. I always demand Lacie Quadra or 2big drives if the production can't afford a proper Raid. I've never come across any external drives from other companies that have the same kind of speed and quality.
Because as it stands, no film has ever been made completely in IMAX. This is as close as it gets. The scenes that aren't filmed in IMAX, are usually shot on 35mm or some digital camera. Filming those scenes in 65mm will bring you a lot closer to the fidelity of IMAX. The jump in image quality won't be as large, and the depth of field will be much closer between the formats as well, whereas the difference between 35mm and even 65mm, let alone IMAX, is absolutely massive.
There's also the bragging point of being the most high-res film ever made :). Tons of films have mixed 35mm with IMAX, but none have done it with 65mm.
It hasn't been shot on Alexa 65. It's shot on Alexa XT...
If you're so invested in having digital be accepted, why shoot down film? They're creative tools that do different things well. If you don't like it, fine! But for many of us film still represents something different and hopefully it will never die.
