Over at The Endless Faculty Meeting a few days ago there was a post about classic film trailers that can be used for educational purposes. The trailers are part of the Digital History website and can be found here.
As an ESL teacher, I am constantly looking for prompts and activities for my students and I think this is going to be great! Some of the movies aren't "classic" or "historically significant" in my opinion, but so what? They have clips from films like "Gold Rush", "The Day the Earth Stood Still" and "The Littlest Rebel" alongside more modern films such as "Big", "Bill and Ted's Excellent Adventure" and "Rising Sun". I know I will be using this site a lot this coming year. Why don't you check it out?
