Viggo Mortensen gave an interview to The Times Of London, and in it he said that he was tired of doing movies. Well, actually what he said was that he was tired of doing everything that is associated with the business of making movies other than the actual filming. He doesn't like doing the press and promotions for movies and all of the travel that entails.
“In the past week I’ve been from LA to Japan to Korea to Poland to here,” he hisses, describing in near disbelief the travel itinerary for his current promotional tour. “It’s ridiculous! It’s not a healthy way to be. But, as it happens, I’m taking measures to change that.” Which are? “No more movies. I haven’t said yes to one in over a year. I’ve been in all these well-received movies and it seems like I should be doing some more, but there’s other things I want to do. It’s not the right time.”
He has had a good run and he has made a bunch of money. Unlike the scam that is Joaquin Phoenix, I actually believe Viggo. He does have one more movie in the pipeline which he already completed. If he is still making these comments a year after not accepting any roles, than I would say he probably has another year break left in him.
I don't think he is gone forever. He definitely doesn't need the money, but I think there will be a time where he misses doing movies and will get excited about a project and be willing to make the sacrifices again. In the meantime, better enjoy his last movie which will be The Road.
