The F/x in the walking scene is obvious as the scenery is moving faster than the trio walking.
Lionel Barrymore was permanently disabled at time of production. Swaying side-to-side was to give the impression of moving with a film background moving towards them in one perspective, and moving right to left as they seem to go left to right.
However, the film background was moving way faster than Barrymore appeared to be moving. It was a jogging pace as Barrymore was going baby-steps.
Pretending to walk with F/x was not a mistake, yet moving faster than the actors ruins the movie's magic illusion.
