Not from my 25 years experience. They are hard rubber. Not easy to tell the difference. If I thought it was routine. I wouldn't have thought it worth mentioning. Interesting enough, I've worked on a film set the Alec Baldwin. He could be intimidating at times. He even fired a set photographer because he was getting in his eye line. It was on the set of Nuremberg shot back in 1999. Personally, I think the man is a good Actor.
