In an interview with Asylum's Anthony Layser, Doyle talked about writing Duplex, a Ben Stiller/Drew Barrymore comedy that DeVito directed -- poorly, says the scribe:
"It was fun up until Danny Devito was hired to direct it. As far as I can tell -- and I'm not sure about the legal basis for saying this -- but as far as I can tell, Danny Devito is a world-class d**k. Just like an incredible a**hole, at least when he's a director. I believe that's not even at the level of gossip. I think that's a fairly well-established fact. I think he's a fairly sweet guy as an actor and in person, but...
"I was not privileged to actually be on the set of the movie, because I was invited to the movie by Ben Stiller's producer and then later in the day, disinvited by Danny Devito's producer. He called to say that I would not be welcome."
Danny DeVito, he does not love your work. Here's the video:
