Factual error: Young David focuses his telescope at the moon. A close up shot then shows a circular view i.e. it is supposed to be the view through the telescope. Both the moon and the clouds in focus. With a telescope the depth of field is short and, with the moon in focus, the clouds would actually be blurred.

Joseph Finley: I feel great.
Ben Luckett: You wouldn't bullshit me?
Joseph Finley: My God, I'm telling the truth.

Trivia: Some of the cloud effects were created by dumping colored dyes in tanks of water which were then superimposed into the shot.
