Corrected entry: SPOILER ALERT. In Bill and Ted's Bogus Journey, Death was able to bring Bill and Ted back to life because their bodies were still fresh and undamaged, and he was able to put their spirits back in. In this film, Bill and Ted, their daughters, Ted's dad and the historical musicians were all vaporized which meant they would have no bodies to return to and would have been stuck in their spirit form when Death returned them to earth. But for no explainable reason, they all come back in human form.

Correction: The bodies were not a factor in their resurrection. The Reaper was also able to resurrect Station, who were a pair of aliens who had no bodies on Earth.
