SNL writer and actor Mike O'Brien shared a moving photo of Villines, writing, "On our left there is my good friend Matt Villines (of "directed by Matt & Oz") lining up a shot for the Snl short, Monster Pals. I'm extremely sad to say he passed away last night. He was one of my favorite people. He taught me a ton about filmmaking and even more about being kind even when you're stressed or frustrated or sick."
"I'm going to post a handful of photos of him this week and I hope those of you who knew him will do the same," O'Brien added.
"I love you @mattandoz," tweeted current cast member Aidy Bryant.
