“Battlestar Galactica” fans were stoked to see the cast of the hit sci-fi drama reunite at Comic Con International, but the occasion is equally exciting for the stars themselves.

“It’s a rare instance when the cast and crew are almost as close now, as we were when we finished,” Tricia Helfer tells ET Canada in San Diego. “Katee Sackhoff is one of my best friends, Michael Trucco is — I was at his house yesterday dropping off a power washer that I was borrowing! We are really, really, incredibly close.”

While the stars have maintained strong relationships since the series ended in 2009, some of the cast have been busy with other projects that have kept them away from the gang.

“There’s Vancouver-based actors, and Grace [Park] has been in Hawaii for years, so to have Eric Douglas here and Tahmoh [Penikett], who aren’t always part of the LA group, that makes it extra special,” Helfer says.

As for Park, who recently departed “Hawaii Five-0” alongside Daniel Dae Kim after CBS would not match their salaries to their white co-stars, she says “Battlestar” was ahead of its time in terms of diverse casting.

“[They were] trying to tell a story that’s not limited to a certain period, with a certain group of people or a certain look,” she says. “We didn’t know if it was gonna be in the future, or in the past, or an alternate universe. So part of telling that story is to bring in other races.”
