In this edition of This Week in Blu-ray, we’re going travelin’. We will take a trip to Mars, where a resourceful astronaut has been stranded and must breath with the aid of yellow rocks. We will head out west, where the story for Avatar was birthed by Kevin Costner. We will head back in time, when things were simple and Facebook didn’t rule our lives. And we will travel to a miscellaneous Spring Break destination, where a bunch of agitated pre-historic Characiformes are waiting to take a bite out of our favorite porn stars’ silicon implants. And Jerry O’Connell’s junk. Of course this will all make sense, as long as you hit ‘read more’ below and check out this week’s Blu-ray slate.
