Riz Ahmed plays a drummer who loses his hearing in 'Sound of Metal.' To prepare for the role, he immersed himself in deaf culture — an experience that changed the way he thought about communication and listening. The film earned him a Best Actor Oscar nomination. Also, we listen back to our 2019 interview with actor Kathryn Hahn. She's known for her roles in 'Parks & Rec,' 'Mrs. Fletcher,' and 'I Love Dick.' Now she's co-starring in 'WandaVision' as a nosey and mysterious neighbor. "The most complicated and messy roles I've been able to get have been offered through women," she says. "I'm just so buoyed and galvanized that the juiciest part of [my career] has been post-kids."
