While celebrities going incognito at Comic-Con has become something of a Comic-Con trope, Adam Savage still manages to do it the best. This year, real-life astronaut Chris Hadfield tagged along.
After nearly suffering heat stroke at the 2014 event, Savage made some much-needed adjustments to this year's costume -- a spacesuit from Stanley Kubrick's 2001: A Space Odyssey. Chief among the adjustments: fans and cooling hoses.
According to an interview with EW, Savage has been working on the costumes for five years.
