Olivia Swann

Q: I love the actress who plays Michelle Mackey on “NCIS: Sydney.” Where else can I see her?

A: There’s really just one other place. Prior to helping launch “NCIS: Sydney” in 2023, Olivia Swann was a lead character on “DC’S Legends of Tomorrow” for three years, from 2019 to 2022.

She played Astra Logue, a character with the kind of wild backstory that’s typical for a comic book show. She was accidentally banished to Hell, where she eventually took over to become Queen while also wreaking havoc back on one version of Earth. (I told you it was wild.)

That really was her star-making turn, and other than that she hasn’t been in much.

She had a role in the direct-to-streaming drama “River Wild” last year and has done single episodes of a couple of British shows (“Doctors” in 2018 and “The Break” last year).

Those last two items might seem surprising if you don’t know that Swann, who plays an American investigator working in Australia on “NCIS: Sydney,” is actually from neither of those countries — she’s from England.

She said she enjoys all the traveling that has come with being a TV star. “I do not have a problem uprooting and going somewhere else for work, so having the opportunity to move to Sydney for five months and film was a dream come true,” she told New Zealand’s Stuff magazine.

“NCIS: Sydney” is the first international edition of the hugely popular CBS procedural franchise, and the fifth version overall (after the original one and three other location-based spinoffs in “Los Angeles,” “New Orleans” and “Hawaii”). It’s already been renewed for a second season.
