Jon has been a film nerd from a very early age, and a technical nerd since his family bought their first computer back in the early 80s. He's somehow managed to get himself married and have a baby despite spending most of his spare time in a dark room sitting at a computer. He started the website moviemistakes.com in 1996, listing mistakes from movies, with just a few entries, and over time it grew...and grew...and grew, currently standing at over 100,000 mistakes from thousands of movies and TV shows, together with trivia, quotes, questions and answers, and more.
