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.”

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.

I will miss him more than the limits of my language can tell and my heart can bear. My world is that much fuller because I knew him and that much emptier now that he’s gone.”
