Liza Lapira

“Traffic Light’’ star Liza Lapira likes the get-up-and-go of Boston that she enjoyed while filming “21” here in 2007.

“It’s great to be back,” said the Queens-born star of the new Fox TV comedy during a sit-down yesterday at the fab Four Seasons. “The first thing I did after leaving Logan was take a run around the Charles. I love it here because you can just get on the train and go.”

And that’s just how she got started in the acting world.

“I fell into it. I would just get on the train and go into Manhattan for auditions,” she said.

After landing a role as a backup dancer on a Nickelodeon kids show, Liza was well on her way. Since then, she’s appeared as a series regular on “NCIS” and cult fave “Dollhouse,” co-starring Watertown homegal Eliza Dushku.

“Eliza is very proud of her Boston roots!” laughed Lapira, who hung out the other night with local scribe Ben Mezrich — who wrote “Bringing Down the House,” the book that inspired “21” — and his wife, Tonya.
