Time Machine - S1-E5
Corrected entry: Before Al uses the Time Machine for the first time, the clock/Time Machine reads 11:32. He then sets it to return thirty minutes into the past. However, when he finally returns to his cave, the clock reads 11:30, 32 minutes into the past.
Corrected entry: When Al is talking to Corky from Paris, the fountain behind him, on the left, is still.
Correction: That would be because he is in a television studio, with a supermimposed still photo as the background.
Corrected entry: While Al is preparing to leave, Huey asks if he is going to say goodbye to his stalagmites, and Al looks up. Stalagmites grow from the ground up, and Al would have looked at eye level or below.
Correction: Character mistake.
Correction: The Time Machine is shown to be unreliable and prone to breakdowns. This is just another of its failings.
