The real-life friendship between David Giuntoli (the star of NBC’s Grimm) and German DJ and YouTube personality Flula Borg is reflected in the plot of their new movie Buddymoon. Both actors share their characters first names in this story of an actor (Giuntoli) whose canceled wedding does not stop him from going on the honeymoon he had planned — a hike through the mountains of Oregon — but with his eccentric pal (Borg) instead.

“Flula is my very good friend,” Guintoli tells EW. “It’s one of the best genesis stories for a friendship you can imagine. I was 21 or 22 years old, just post college, and we met while I was hiking around Europe. And apparently, according to his version of the story, I told him to come visit me someday in California. And then, sure enough, he just showed up. He’s a unique specimen.”

“I lived on his porch for some time,” Borg says. “It’s a very small, strange world.”

But did working together spoil their friendship in any way? No, according to Borg, except that he learned a valuable lesson to staying (relatively) sane and good-spirited while working. “The one thing I was taught was that I need more snacks. Snacks are very important to staying friends. We shot in Oregon and I think our total budget was $50, but that was just enough to go to Trader Joe’s every morning and save our friendship.”
