Factual error: The Avalon generates its gravity by rotating, which is made evident by the fact that the elevators connecting the three helical pods are without gravity. When the passengers go spacewalking, the instant they walk out the airlock, they have to be secured by magnetic boots. When they turn them off, they become weightless. Both assertions are wrong for the same reason: If the gravity is created by centrifugal force, that force is present on all points of the ship with the strength depending on the distance to the hub of the ship, no matter whether that point is inside or outside the ship's hull. That of course includes the ledge in front of the airlock. Any surface that is oriented towards the hub of the ship is felt as "floor", surfaces radially oriented to the hub would feel like "walls", surfaces oriented away from the hub would be "ceilings." So if you step off a ledge on the outside of the ship the way the actors do, you'd be drifting away from the ship on a tangent to the ledge you stepped off, and end up hanging by your tethers. You wouldn't accelerate away from the ship like you would in a real gravity field, but you would float away with a speed equal to the acceleration simulated by the artificial gravity. The only way to become weightless would be to cancel the sideways motion imparted by the rotation of the ship. At the rotation speeds depicted in the movie, that would take at least a motorbike to do.
