The hugely popular show, which was set in NYC, lasted for eight seasons before it was canceled. It was originally reported that the show would continue onto season nine without one of the main stars, Stana Katic, which was met with controversy from fans. The show was subsequently canceled, shortly after ABC confirmed that Nathan would be returning for season nine.

Speaking about the situation to Stana previously said: "I’m actually still not clear on the thought process behind the way that it went down. It hurt and it was a harsh ending… I met so many beautiful people on that project, and we collaborated on something really unique in that it’s not every day that you get a show, or a series, that has eight seasons and that it was a hit for the network.

Would you like the show to come back?

"It would be a disservice to those people, to the work that we did together, and to my work, which I feel contributed, in part, to the success of the show, to be anything but grateful because, at the end of the day, that was a fantastic platform. It was a formative experience, and we told a love story that I feel moved people, touched people, and I can’t be anything but glad that I was a part of something like that. I hope it remains something special in viewers’ minds forever."
