Kyle MacLachlan, who was David Lynch ‘s FBI agent Dale Cooper from Twin Peaks, Paul Atreides from Dune and Jeffrey Beaumont from Blue Velvet, took to social media Thursday to express his sorrow over the death of the filmmaker who made him a leading man across TV and film.

We were talking about ideas,” the Twin Peaks and Blue Velvet star says. “It was like, ‘What’s next?’ And then, suddenly—poof—he’s gone.”

MacLachlan said of his career-long friend and collaborator, "I will miss him more than the limits of my language can tell and my heart can bear."
