United Kingdom, July 18 -- Joshua Jackson is "bummed out" by the cancellation of Doctor Odyssey.

The 47-year-old actor had a great time filming the medical drama and has been left mystified as to why it was axed by ABC after just one season, despite giving the network its most-watched debut drama in five years.

He told People magazine: "I'm always bummed out when a show gets cancelled. I really, really enjoyed the experience.

"That was a really good group of people, and it was a really fun show.

"But this is a crazy and difficult business, and whatever the reasons were for them not wanting to move forward with it, they don't actually tell us those things.

"I'm going to miss the gang for sure."

Joshua is "sad" he won't get to return ...
