If you’re big fan of cheesy movie trailers, then this is probably a sad day for you. Don LaFontaine died of what is said to be complications from pneumothorax. However, if you have a really deep voice and you can say "In a world…" in a really serious way, then this might be the day you’ve been waiting for.
Don did a ridiculous amount of talking over the course of his long career, doing countless movie trailers and more commercials than a washed up reality TV star. Now, I never met him or saw him in person or even thought about him until he died, but I can easily say that his passing is the biggest national tragedy in the past 100 years. Nah, just kidding. It is sad, though.
