Stellan Skarsgård doesn’t believe in bad guys

Aside from the evil Baron Harkonnen in ‘Dune,’ actor Stellan Skarsgård doesn’t really believe in bad guys. He looks for nuance in every role. He’s Oscar-nominated for his performance in ‘Sentimental Value,’ as a successful filmmaker who is estranged from his grown daughters. Skarsgård spoke with Dave Davies about improvising with Robin Williams in ‘Good Will Hunting,’ raising actor children, and how a stroke impacted his acting. Also, critic Maureen Corrigan reviews ‘This is Not About Us,’ by Allegra Goodman.
