If you're wondering why I'm showing scenes from Tron in class, it's because the chapter in their textbook is on CGI and movie special effects. There's not really much you can do with this scene ESL-wise; you can probably play Twenty Questions about where they think the guy is and who he's racing. Otherwise, I think it's best saved for an end-of-class time filler or mid-class "brain break."
If you want to save this or any YouTube video offline, I recommend YouTube Downloader HD. For other (and honestly, better) videos, there's always my other Multimedia Monday posts.
