This is good for a laugh. You may remember a brief trend for editing movies to make trailers that show the movie as a completly different genre like The Shining as a life affirming dramedy or West Side Story as a zombie movie (links to the best ones here).
Anyway, there’s a new one to take a look at named Brokeback To The Future. If you find the idea of Heath Ledger mounting Jake Gyllenhaal repellant just think about Christopher Lloyd getting freaky with Michael J Fox as star-crossed lovers across time. Suddenly sounds more appealing, doesn’t it?
