Film: American Werewolf in London (1981) Directed by John Landis.
After watching this film for a few minutes, I realized that I had put it under the wrong theme. For future viewers, this funny is so funny! I was laughing through the whole thing. This film was so amazing!
One of the features that gave me the "WOW" factor, were the animatronics that were used. The transformation that David took from human to werewolf were amazing. It really seemed like he was changing. Instead of modern use of CGI, this film uses robotic masks to make it seem like his body is growing. Using animatronics instead of the computer makes it all seem more real. Doing the animatronics made it easier to actually watch David change, rather than splice together different images of him changing. The director could have one continuous shot.
Even the special effects of Jack's undead look was brilliant as well. Over the course of the film the undead Jack continues to decompose and the make-up was over the top spectacular. His face really did look like some monster scraped half of it off. All of the other characters who were killed by David also looked very dead as well.
I enjoyed the story plot too. Two guys traveling Europe together alone is just asking for trouble, and that's what they got. One died and another became a monster feeding off other people. Tie all that in with the dead walking around (not as zombies) and a love story and you have yourself a bonafide compelling plot. The story was good and interesting and made it fun to watch.
