Gravity Falls creator Alex Hirsch recently addressed the possibility of a future crossover with Rick and Morty.

Do Gravity Falls and Rick and Morty exist in the same universe? Rick and Morty has included minor Easter eggs referencing Gravity Falls and vice versa, including Bill Cipher and this mind-blowing portal continuation.

Hirsch spoke with Entertainment Weekly recently about the Easter eggs present between Gravity Falls and Rick and Morty, the latter of which is run by his former colleague Justin Roiland.

How Will 'Rick and Morty' Move Forward Into Season 3?

"There was a time when Justin and I were both working in the same tiny office for the Disney Channel. We both dreamed one day of having our own weird TV shows, and we would talk about ways in which we would childishly abuse this power. For some reason, the universe has blessed us with our mad wishes, and it occurred to us - let's start doing things that nobody else does, that maybe you're not supposed to do," Hirsch explained. "We started putting little easter eggs in our shows that sort of connected the two. Our motivation for that is primarily to freak people out and blow their minds. The impression of a grand brilliant design is probably more something that the fans have invented."

It may not seem likely that we'll see an actual crossover between the two shows, but never say never.

"I remember when I was a kid, whenever you'd see cartoons cross over with each other, it always ranged from a delightful, magical surprise to a cynical, annoying cash grab," Hirsch recalled, when asked about a straight up crossover. "So far, we've found that these little winking nods between our shows strike the right balance. I can't say whether or not there will be more, but I can say that we like to confuse and amuse people so who the hell knows."

Of course, Rick and Morty is a product of Adult Swim while Gravity Falls is a Disney production so rights may be an issue. But anything is possible.

Meanwhile, Rick and Morty does not yet have a season 3 premiere date.
