About five years ago, Seth Rogen posted a picture on Instagram of seven rudimentary clay objects with the caption: “So maybe I joined a pottery studio so I could start making my own ashtrays.” Now, he’s taken his love for pottery to the next level by signing up as an executive producer for the competition show “The Great Canadian Pottery Throw Down.” He also appears throughout the series as a guest judge. Seth tells Tom what inspired his love of pottery, if he finds it therapeutic, and how the imagery and design around weed paraphernalia has changed since legalization.

Newfoundland’s own Alan Doyle is one of Canada’s great songwriters. He sits down with Tom to celebrate the release of his 20th album, titled “Welcome Home,” and reflects on the early days of his band, Great Big Sea.

The actor Paul Giamatti (Sideways, Private Parts) has reunited with “Sideways” director Alexander Payne for the new film “The Holdovers” — and now he’s nominated for best actor at the Oscars. Paul talks to Tom about the nomination, growing up in an academic world like his character in the film, and what sets Alexander apart from other directors.

The rapper Vince Staples can kind of do it all, even if he doesn’t see himself as any sort of celebrity. “The Vince Staples Show,” which Vince wrote and stars in, just might change that. It's a funny and honest semi-autobiographical story about a guy named Vince Staples who’s navigating fame while also rubbing up against his past life in Compton and Long Beach. Vince tells Tom all about it.
