1. Jurassic Park/ Jurassic Park is one of my favorites mainly because it is the first movie I remember seeing in theaters, I mean what else does a 5 year old like then Dinosaurs and now that I'm older and understand a lot more I always liked the way Spielberg used CGI and animatronic so effectively I would hope if I where to get a directing position one day that I can pull off something that awesome.
2. Terminator/ Terminator 1 and 2 is one of the best of James Cameron's films, but the reason it is one of my favorites is the fact that when someone thinks the world is going to be taken over by machines 9 times out of 10 your mind goes to Terminator.
3. Ghostbusters/ Ghostbusters is one of my all time favorite comedies Bill Murry, Dan Aykroyd, Harold Ramis, Ernie Hudson all in their prime what is not to love. besides that one of the coolest cars to ever be the Ecto-1 a Miller-meteor Ambulance/Hurst.
4. Back to the Future/ Micheal J. Fox is an great actor and the Delorean time machine is only second to the Ecto-1 in cool movie cars.
5. Mad Max/ Mad Max is to me quintessential post-apocalyptic movie of all time almost every movie that has come out about post-apocalyptic world takes ques from all three movies.
