The 39-year-old actor stopped by The Ellen DeGeneres Show -- airing Monday -- when he was actually interviewed by Miley Cyrus, who filled in for DeGeneres while the comedian was under the weather. Ventimiglia talked about his new family drama, which drew more than 10 million viewers to its debut earlier this month. The series has already scored a full-season pickup, NBC announced last Tuesday, bringing its total episode count to 18.
"It's got heart," Ventimiglia said about the show's appeal. "You know what I love about it? It's hopeful. There's a whole landscape of you know, aliens invading planets, and scandal, and this is inherently good."
ET spoke to This Is Us creator Dan Fogelman last week, who previewed what's next for this season's big breakout hit.
"The next three episodes are really, really strong and there’s an emotional response to the characters and the material," Fogelman told ET exclusively. "Hopefully, in its own unique way, that can draw people in a different way to TV, like the way I was drawn to it as a little kid.”
