Timeless will premiere on NBC this fall, and there is a special guest star recognizable to fans of Once Upon a Time set to appear on the series this season. According to Entertainment Weekly, Sean Maguire has been cast as Ian Fleming, the man that created James Bond.

Maguire will be featured in “the fourth episode, titled ‘Party at Castle Varlar,’ the heroic trio led by historian Lucy (Abigail Spencer) will encounter Fleming early in his pre-Bond career, when he served as an undercover British agent behind enemy lines.”

Eric Kripke spoke about the decision to include Fleming on the series. He said the following:

“We knew we couldn’t just do a war movie, so where we landed was, ‘Alright, then let’s do a spy movie. We needed a spy in Germany to help our heroes and bring them into this world… and we turned to our historian, and he said, ‘Let me work on it,’ and then he comes running in the room an hour later and says, ‘Ian Fleming was there!’ So, quickly, we realized our World War II story was really a James Bond movie, and we had the real James Bond.”

As for Maguire’s Once Upon a Time fans, will he ever return to the series? Robin Hood died at the end of last season. A previous Entertainment Weekly report shared comments made by Edward Kitsis. He said the following:

“After the panel, the OUAT bosses clarified what they meant about Robin Hood. ‘The question was whether or not his spirit has moved on or is his soul truly obliterated,’ Kitsis told EW. ‘What I was saying on the panel, perhaps not clearly enough, was that I choose to believe that Hades was lying and that Robin Hood’s soul had moved on being such a good person.’ Added Horowitz: ‘The characters should and hopefully will question what Hades says and whether that’s true. That doesn’t mean we’re bringing Robin back. He died.’”
