Not so sure I would consider Memento a time travel movie... just a unique way of unraveling the storyline. Fantanstic movie, btw. Have you seen Primer? Low budget, but unique way of looking at time travel.<br /><br />Combining both genres, I would 2nd Vogon's pick of Alien. I also like Jurassic Park if you consider dino's as monsters.<br /><br />Stand alone Sci-fi: Star Wars, Empire Strikes Back, 2001, but If I had to pick only 1, I would go with Contact.<br /><br />Good old fashioned monster movie? Kinda hard to pick as I'm not a huge fan, but The Fly (Goldblum remake) was cool, though that's a bit of a sci-fi/monster combo. Can I pick Silence of the Lambs?... Lecter was quite the monster. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>
