Is the film Beerfest (2006) the first film to depict the playing of pong? (See The Dartmouth;Wikipedia.) The characters appear to use paddles, but the film’s creators learned the game at Colgate.

Daniel Lindsay, director of a post-9/11 documentary titled Why U.S.?, is directing a film meant to document pong and its history on a national scale, according to an article in The Dartmouth. He and producer Josh Otten were in Hanover gathering material in November.
