Grace Park has been part of the main cast of "A Million Little Things" since the TV series debuted as part of ABC's fall 2018 season. The drama centers around a group of friends in Boston who are shocked when one of them, Jon (Ron Livingston), dies by suicide. The gang tries to make sense of what happened while they also take stock of their own lives.
This includes Katharine Saville (Park), a party girl turned career lawyer trying to repair her marriage to Eddie (David Giuntoli). Park said that she liked how Katharine wasn't always an appealing character, saying that "Not everyone might like her, and I thought that was actually quite a relief of pressure, that you didn't need to make your character funny or likable or cool or sexy or the lead" (via Entertainment Weekly).
Overall, the veteran TV actress seems happy to be in an environment that's very different from the sunlit crime drama of "Hawaii Five-0," and more importantly, hopeful. She told EW that "I'm good leaving the boys' club, and I'm hopeful for the future." Alongside her main role in "A Million Little Things," Park also starred in two films, "Adventures in Public School" and "Freaks" (via IMDb).
