Watch this awesome video of “MythBusters” star Adam Savage going incognito at San Diego Comic Con in an “Alien” costume that took him 10-years to make!

Nearly unrecognizable, Savage patrolled the con floors, posed and took pictures with other con goers in his Alien replica costume.

“I just walked the floor in my Alien spacesuit from Ridley Scott’s movie and it was the hottest and most balmy experience of my life — I think I lost three pounds just walking for 30 minutes,” said Savage.
