If you missed this Summer's female buddy cop comedy The Heat with Sandra Bullock and Melissa McCarthy, you'll have a chance to check it out when it comes out on DVD and Blu-ray this week. We have a look at one of the extras — a blooper reel of Bullock and McCarthy cracking each other up — and even if you haven't seen the movie yet, you'll want to watch this — because who doesn't love a blooper reel? The actresses can't keep their giggles in, and you won't be able to either.
