Question: Is there a scene where a young boy watching the filming is seen? I heard this years ago and the clip was shown.
Question: When Richard accidentally pulls a coin out of his coat pocket, he sees that it's a penny and he is sent back to his own time. After being weakened upon his trip back to the future, why, after what was likely several days to get his full strength back, wasn't he able to return to the past? His mentor told him returning to his own time would leave him weakened but, given enough time to get it back, he could have gone back to the past again.
