In honour of next week’s release of Source Code on DVD and Blu-ray, and because it’s one of my favorite topics, this week for DVD Tuesday I’m counting down the ten best time travel movies. From science fiction, action, adventure, and horror, to comedy, and even a romantic comedy or two, these movies cover almost every genre, and I’m ranking them not just on how great the movie is, but also, how well they approach a time travel story.
