Just like most good pairings on TV, Dominic Purcell said that his chemistry with his “Legends of Tomorrow” co-star Wentworth Miller is something that is not manufactured.

“People have often spoken about the chemistry between Wentworth and myself. I mean, I can’t articulate it, but I think it’s one of those things,” Purcell told Stevivor. “It’s an accidental surprise really. It just works.”

The 46-year-old actor added that their longtime friendship has also helped them a lot in understanding each other much better when filming a scene together.

“With Wentworth it’s just a complete trust; complete understanding,” Purcell said of his working dynamic with Miller. “And there’s no feeling-up process. I mean, we’ve worked with each other for — well, ‘Prison Break’ — and we’ve known each other for close to 12 years now. And we’re very close, good friends, and that enables us to just relax.”

In fact, in a separate interview with Collider last January, Purcell mentioned that he considers Miller his family.

“We just know each other’s acting rhythms and personal rhythms so intricately,” he told the website when asked how their real-life relationship adds to the dynamic between their “Legends of Tomorrow” characters Mick Rory (Purcell) and Leonard Snart (Miller). “We know each other very well. He’s one of my closest friends. I consider him family. When we work opposite each other, it’s just there.”

Unfortunately for the fans of the duo, “Legends of Tomorrow” Season 2 will feature less of the pair, as Deadline reported last May that Miller will no longer be a series regular in the sophomore run of the “Arrow”-“The Flash” offshoot.

The death of Miller’s character at the latter part of Season 1 explains the status change for the 44-year-old actor. Although Miller won’t be a permanent fixture in Season 2, Deadline revealed that he entered a series regular contract with Warner Bros. TV, with his duties spread over different DC Comics shows developed by Greg Berlanti.

Also, given the time-travel nature of “Legends of Tomorrow,” Leonard’s death is not permanent. In fact, it was confirmed at the San Diego Comic-Con last July that Miller is set to return to the series as part of the villainous group Legion of Doom.

“Legends of Tomorrow” Season 2 premieres on Thursday, Oct. 13 at 8 p.m. on The CW.
