It seems DoComo’s viral marketing campaign featuring Star Wars villain Darth Vader was for the Samsung Galaxy S – exclusively offered by them in Japan. Following an announcement of the device (with a real life Darth Vader on stage), Samsung let loose this promotional video of Vader creepily following people around. The first thing that came to my mind was “so if I buy this phone, creepy men will stalk me?” I’m sure that’s  not the message DoComo was spreading, though. Instead, it sounds like they want you to know that, as your phone is always with you, so is the force. And creepy men with Darth Vader costumes. Just watch the video. [via MobileCrunch]
