Babbage is a short 15-minute film, an imaginary dinner with people from his life including Herschel, Ada Lovelace and his wife. Here is the Wikipedia entry for the film.
Perfect for introducing some of the concepts he came up with when discussing coding.
Charles Babbage (26 December 1791 – 18 October 1871) was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage, along with Ada Lovelace, is best remembered for originating the concept of a programmable computer. Considered by some to be a “father of the computer”, Babbage, along with Lovelace, is credited with inventing the first mechanical computer that eventually led to more complex designs. His varied work in other fields has led him to be described as “pre-eminent” among the many polymaths of his century. Parts of Babbage’s uncompleted mechanisms are on display in the Science Museum in London. In 1991, a perfectly functioning difference engine was constructed from Babbage’s original plans. Built to tolerances achievable in the 19th century, the success of the finished engine indicated that Babbage’s machine would have worked. Wikipedia
