In summary, authoritative major news outlets and widely recognized sources have reported on Nathan Fillion playing Guy Gardner and discussed his character traits and his own comic book fandom, but there is no clear evidence from these sources confirming the exact headline or claim about "decades of Green Lantern roles" reflection combined with "record-breaking profanity."
