Back to the Future, by Robert Zemeckis, is full of wonderful original ideas. But the key scene where Doc is on the clock trying to connect the cable was definitely taken from another film.
The most attentive viewers noticed that almost the exact same thing happened to Harold Lloyd in his 1923 masterpiece Safety Last!. You can watch the opening minutes of Back to the Future where you will see a clock with Lloyd on it.
one does not _have_ to be here
Feedbacks are important though. If I do something wrong I want to know, not just wonder about why am I always alone.
