Michael Emerson, best known for his roles on Lost and Saw, will head to Arrow this season in an as-yet-undisclosed role -- and nobody is more excited about it than Arrow executive producer Marc Guggenheim.

Guggenheim, who has a history with Emerson, told ComicBook.com during a red carpet interview at Comic Con International last week in San Diego that he is working with the actor to create a complex and multifaceted character that Emerson will be excited to play.

“We’re just lucky to have him on the show, quite frankly. We’ve been huge fans of his — I actually worked on The Practice when he created the Mr. Hinks role, and it’s been a personal bucket list item of mine to work with him again,” Guggenheim said. “We are talking about him playing a character who’s got a lot more nuance than the typical creepy-guy role that he is often cast in. We’ve had a lot of creative discussions with him, and I think that’s one of the things that has excited us and excited Michael: that we really want to create a character in consultation and in conjunction with him. It’s not just ‘here’s the script — go!’ It’s a really interesting, two-way back and forth.”

The series will return in October, although it is not yet clear when Emerson's character will first appear.

After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea. He returned home to Star City, bent on righting the wrongs done by his family and fighting injustice. As the Green Arrow, he protects his city with the help of former soldier John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), his vigilante-trained sister Thea Queen (Willa Holland), Deputy Mayor Quentin Lance (Paul Blackthorne), brilliant inventor Curtis Holt (Echo Kellum), and his new recruits, street-savvy Rene Ramirez (Rick Gonzalez) and meta-human Dinah Drake (Juliana Harkavy).

Oliver has finally solidified and strengthened his crime-fighting team only to have it threatened when unexpected enemies from his past return to Star City, forcing Oliver to rethink his relationship with each member of his “family”.
