It’s no secret that Adam Savage of Mythbusters likes making costumes and dressing up, and for Halloween this year, he tackled an outfit from a popular movie: Ghostbusters. The film is celebrating its 30th anniversary so there’s no better time to join the Ghostbusters team. Savage reviewed the ins and outs of his costume with Tested and showed off his light-up proton gun and proton pack. He built it from kits and bought and modified the jumpsuit. He mentions turning to The Replica Props Forums for research and reference a few times.
