Movie Mash Ups

Recently encountered&quot;Edge of Tomorrow&quot; which is in my estimation a mash up of Ground Hog Day meets Aliens. <div><br /></div><div><br /></div><div>We all know Hollywood is notorious for doing remakes that don't need to be done and screwing it up. But I'm rather taken with this somewhat remake of Groundhog Day, a classic I rather liked. </div><div><br /></div><div>So my question is classic movie Mash ups as sci Fi adventures: what's your suggestion?</div><div><br /></div>
