10 Hidden Details In Gravity Falls You May Have Missed

10. Hidden Celebrity Cameos

There are certain celebrities who have lent their voice to Gravity Falls and it may have gone unnoticed because you can't put the name to face. The obvious examples are Larry King and Coolio who play their own waxed figures.

In the episode Dungeons, Dungeons & More Dungeons, Weird Al Yankovic provides the voice of the adversary Probabilitor the Annoying. Star Wars alumni Mark Hamill portrays the mysterious old man, amongst various other characters. Brooklyn Nine Nine's Chelsea Peretti plays Darlene - a spider who can disguise herself as an attractive woman in order to lure in men.

And additionally, Lance Bass, member of real-life boy band N*SYNC, lends his voice to the fictional boy band Sev'ral Timez. This is a little in-joke because Sev'ral Timez are a parody of the boy band culture rampant during the 1990s.
