HAL attacks Frank
We don’t see the actual pod assault… only the aftermath.
I used to hold the assumption (possibly suggested by Kubrick’s jump cut direction) that Hal just simply rammed Frank, and that was enough to send him tumbling away.
Now I’m starting to imagine a much more violent struggle, with Hal grabbing at Frank with the pod arms, ripping at his O2 supply, Frank fighting back , and then HAL hitting the thrusters to really accelerate Frank away from Discovery, in the process inducing an uncontrollable tumble in both Frank and the pod.
How do you see it happening?
