Factual error: On board spaceship Discovery, the crew's living area is the spinning centrifuge, which spins about its axis to generate a gravity-like acceleration at its perimeter, the floor. When exiting the centrifuge a crewman climbs a ladder from the floor up to the hub, where there's a door leading to other parts. When Poole & Bowman climb this ladder, it's evident that they're under full body weight the whole way up. But in reality they'd get steadily lighter toward the hub. In fact, they'd be practically weightless within a few feet of it.

Factual error: When Bowman blows the pod hatch and is ejected by the air into the ship's airlock, Newton's First Law dictates that the pod should move in the opposite direction, away from the ship.

Suggested correction: Already posted and corrected - The pod would be weightless in outer space but it still has mass and inertia. The total change in momentum of Bowman and the air escaping from the pod, applied to a pod with about the mass of medium sized car, would result in the pod moving away at only about 50cm per second. That would be barely noticeable from our point of view, even if the change wasn't immediately corrected by an auto-pilot mechanism, which is feasible. We can calculate the reaction speed of the pod this way : assume a gas volume of 4 cubic metres, a mass for the pod of 2500 kg, a mass for Bowman of 150 kg, an average delta v of 100 m/s for the air in the pod, and a delta v of 10 m/s for Bowman - all of which yields a result of 0.5 m/s, and if air pressure in the pod were lower it would have moved even more slowly.

Factual error: In the title shot, the camera rises above the dark side of the moon, revealing the crescent of the Earth, which in turn reveals the full disc of the Sun. The Sun is surrounded by the pinpoint lights of distant stars, but there are virtually no stars visible on the darkened far left and far right sides of the screen. This is exactly opposite of how real-life astronauts describe the star scape: Astronauts say that no stars are visible when looking in the general direction of the Sun, and that stars only become visible to the human eye as you turn away from the Sun.

Continuity mistake: When Dave gets his supper, the order of the slop from right to left is yellow, light brown, light brown, dark brown. Later when he's eating, the order is yellow, orange brown, dark brown, light brown. (00:59:00 - 00:59:50)

Trivia: As HAL loses his mind, he begins to sing "Daisy." In 1961, "Daisy" was the first song ever to be reproduced with a nonhuman voice - a computer.

Question: Maybe I need to read the book, but can someone explain the whole ending sequence to me. Why all the flashy over dramatized pictures? It's artistic but is there some other meaning to it?

Chosen answer: All the flashing images are supposed to represent Bowman travelling past far and distant galaxies, this is what happens in the book, where he travels to that white house place.

Answer: At the end, in the Arthur C. Clarke's story, both Dave Bowman and Frank Poole (who survived) went to a moon of Saturn to investigate the second Monolith. Dave Bowman tried to touch the Monolith with his space pod and was sucked into a wormhole that transported him to a star on the other side of the universe - at which point, Dave's last transmission is "My God, it's full of stars!" All of the "slit-scan" visual effects by Doug Trumbull (based on effects created by John Whitney years earlier) represent an almost instant voyage to the other side of the universe. Whether this is supposed to be a quantum-jump is not explained, but it's millions of times faster than anything ever depicted in Star Trek or other space fantasy knockoffs.
