Corrected entry: Doc Brown can build a time machine but is unable to figure out how to build a still to extract pure ethanol from Whisky in order to use as fuel for the DeLorean. He stated to Clara that he is a "student of all science" so this should include chemistry. Chemists know how to build a still. Doc, however, tried to fuel the car with strong Whisky without distilling it.

Correction: They did not have time to build anything, they were in a hurry to leave before Doc gets killed.
Correction: He would with no problem be able to get that thing to run on ethanol, just a different air fuel ratio bigger injectors so just make bigger holes in the ones you have. Just to run it one time would be no problem.

Back to the Future Part III (1990)
Corrected entry: In the opening scene when Doc wakes up he turns on the TV to hear "Hey kids, what time is it? It's Howdy Dowdy time." Doc, on the phone, says the time is 7 o'clock AM. Any smart baby boomer knows that Howdy Dowdy aired at 5:30 PM EST. (00:05:17)
Correction: Look at the mass of electronics on top of the television. It's likely that Doc has constructed a recording device and is using a recording of Howdy Dowdy as an alarm clock (remember his facination with the modern video camera in Part 1). We also know from the beginning of Part 1 that Doc has an obsession with setting alarm clocks.

Corrected entry: The gravestone as seen by Marty and Doc in 1955 is in the same mint condition as when we later see it being made in 1885. Given that it has remained outside for 80 years, shouldn't it be more weather beaten or damaged?

Correction: He needed a quick solution and thought the whiskey would work. Apparently his expertise does not include the workings of internal combustion engines or he never would have tried it. Pure ethanol would also probably not have worked in the DeLorean.
