That's sad. I wonder what the deeper prognosis is, since aphasia is usually the side effect of other problems (head injury, cancer, disease, etc)
I read an interesting article about him. We all know he's been doing tons of these shovelware movies the last decade, just quick cash grabs on garbage movies really. The article quoted people saying he has had a hard time with his lines for several years, to the point where they just gave him an earpiece (earwig) and someone reads his lines to him to repeat. I had assumed it was bc he didn't give a crap about these 1-2 day shoots enough to read the scripts and he does so many of them. This shines a different light on that.
Anyway he has plenty of money, time to take it easy and hopefully with time, therapy, medication his condition isn't permanent.
