We have all seen and enjoyed the video parodies from 'Downfall' aka Hitler in the Bunker. You may even have seen mine. It's not the easiest thing in the world to do, but equally, it's not too hard either. However, it's now a lot easier, thanks to Make your own Hitler video. You simply add in the subtitles in the boxes that they've put on the screen for you, and it does the rest. You can then upload it directly to your own YouTube account. If you're worried about the legality of doing this, the company that produced the film did at one point try and have them taken down, but they have now decided that it's better publicity for the film, and they have stopped trying to stop people.
It's excellent fun - have a go yourself!
