The 69-year-old actor decided not to join his castmates at a screening of the film and now said that he has cut back his travelling due to his increased anxiety on planes, reported Express online.
"I don't like flying at the best of times. And as I get older, I like it less and less," he said.
Walken said that he also tries to avoid driving and is often plagued by irrational fears during trips abroad.
"I don't much like driving either. I prefer to be driven. And, when I'm in London, I don't even like walking on the street... When we're over there, I always say to my wife, 'Stay in the hotel. Don't go out there. It's too dangerous'," he added.
