Michael Sheen appeared on Chris Hardwick’s The Nerdist Podcast in September 2014, alongside his partner at the time, comedian Sarah Silverman.
A very funny, fascinating, and slightly filthy podcast, covering many different topics, including: Stephen King, being called Martin Sheen his whole life, Welsh Jack Nicholson, Masters of Sex, being a process nerd, The Shawl of Shame, the acting process and vulnerability, 30 Rock, Doctor Who, and The Singing Ringing Tree.
Note that the Nerdist podcast has since been renamed ID10T.
