Jason Fitzpatrick is warranty-voiding DIYer and all around geek. When he's not documenting mods and hacks he's doing his best to make sure a generation of college students graduate knowing they should put their pants on one leg at a time and go on to greatness, just like Bruce Dickinson. You can follow him on Google+ if you'd like.
Before the advent of audio dubbing, films released in multiple languages required (polyglot) actors to shoot each scene over for each language (speaking the words of their non-native language phonetically). Another popular option was the use of multiple sets of actors (a set for each language) to work on language specific versions of the film in shifts. A movie released to English, French, and German audiences, then, would require the entire film be effectively filmed three times.
