First Contact (1983 film)
"First Contact" is the first documentary in what later became known as "The Highland Trilogy". The other two films are "Joe Leahy's Neighbours" (1989) and "Black Harvest" (1992). These three films, between them, have won some thirty major awards, included each film winning both the Grand Prix at the Festival Cinéma du Réel in Paris and AFI Award for Best Documentary.
Animated documentary
The first recognized example of this genre is Winsor McCay's 1918 12-minute-long film "The Sinking of the Lusitania", which uses animation to portray the 1915 sinking of after it was struck by two torpedoes launched by a German U-boat; an event of which no recorded film footage is known to exist. 
Since the 1920s, animation has been used in educational and social guidance films, and has often been used to illustrate abstract concepts in mainly live-action examples of these genres. Early examples of fully animated educational films are "The Einstein Theory of Relativity" (1923) and "Evolution" (1925) by Max and Dave Fleischer. Walt Disney used it in films such as "Victory Through Air Power" (1943), "How to Catch a Cold" (1951) and "Our Friend the Atom" (1957).
