NBC’s “This Is Us” is one of the most popular dramas on network television.

The series tells the story of the Pearson family in a unique way. Parents Jack (Milo Ventimiglia) and Rebecca (Mandy Moore) raise their three children through the 1980s and 90s. As adults, their three kids are played by Sterling K. Brown, Chrissy Metz, and Justin Hartley. The series also stars Chris Sullivan, Susan Kelechi-Watson, Jon Huertas, Eris Baker, Parker Bates, Lonnie Chavis, Niles Fitch, Logan Shroyer, Faithe Herman, Hannah Zeile, and Mackenzie Hancsicsak.

“This Is Us” earned 10 Primetime Emmy nominations for its first season, including Outstanding Drama Series. It has also been nominated twice for the Golden Globe for Best Television Series — Drama. The cast also earned the Screen Actor’s Guild Award for Outstanding Cast on a Television Drama.

Justin Hartley stars as Kevin Pearson, a former high school athlete-turned-actor who leaves his hit sitcom and goes on a search for himself. This road to self-discovery is temporarily derailed by a drug addiction and a trip to rehab. But it also opens him up to face issues from the past.

Hartley got his start in television with a role on NBC’s soap, “Passions” in the early 2000s. He played Oliver Queen/Green Arrow on “Smallville” for five seasons. He appeared on “Revenge,” “Mistresses,” and “The Young and the Restless” before landing what he calls “the role of a lifetime.”

I sat down with Justin a few weeks ago at NBC/Universal’s Summer Press Day. Please enjoy our conversation about his work, the growth he has experienced over the past two seasons, and the show’s outstanding writing.

“This Is Us” will return to NBC this fall. You can catch up on past episodes on Hulu. Justin Hartley and the rest of the cast are eligible for 2018 Emmy consideration.
