"I love you Jeff," Jake wrote in a Jan. 7 Instagram post. "Hate your last move. But still love you."
Alongside the heartbreaking message, the Spider-Man: Into the Spider-Verse star also shared a series of images to commemorate Jeff, who appeared alongside Jake in the 2015 movie Digging for Fire and directed him in 2016's Joshy. In one of the snaps, Jeff looked pensive while sitting at a dining room table among friends as they played poker. In a second pic, the Little Hours director cradled a baby in his arms while donning a warm smile.
According to Los Angeles medical examiner records viewed by E! News, Jeff died by suicide on Jan. 3.
In wake of the tragedy, several of the screenwriter's collaborators and friends have honored him with touching tributes, including Molly Shannon, Brady Corbet, Dane DeHaan and Alison Brie.
Additionally, actor Adam Pally—who starred in Jeff's films Life After Beth, The Little Hours and Joshy—highlighted his "impeccable taste and vision" as a director.
"He was a connector of people, a fosterer of possibility, the guy who knows where the best restaurant was no matter where you were," Adam wrote on Instagram Jan. 5. "An overly gracious host with an almost disturbing open door policy, a film encyclopedia, and most important to me a friend."
