Stephen Amell Reveals Special Guests for Arrow’s 100th Episode

Production is in full swing on Arrow‘s 100th episode and star Stephen Amell has taken to Twitter to continuously tease the episode and its special guests. Among those set to appear in the episode, which appears to be part of the epic four-show crossover, is a guest list that includes Grant Gustin as The Flash, Victor Garber as Martin Stein, Franz Drameh as Jefferson Jackson, Melissa Benoist as Supergirl, and the return of Deathstroke (whether that is another hallucination or the character’s true return remains to be seen). Check out Amell’s photos in the gallery below.

“You really are trying to run a single production across three different productions,” Greg Berlanti previously told Indiewire about the crossover. “But they’re run as three separate entities. We have to figure out when we’re borrowing one actor from where. We’re telling one cohesive story; ‘Supergirl’ will participate, but the storyline doesn’t actively begin there. There are some characters who show up in her episode, but the story begins with ‘The Flash’ episode and goes to ‘Arrow’ and ‘Legends of Tomorrow.’ We’re just getting into designing the bad guy for it, and we start now but it doesn’t air until the end of November. We will put a lot of time between now and then figuring out visual effects sequences. Just today I was holding the three scripts back-to-back – that’s 180 pages of material. It’s a three-hour story, almost a miniseries.”

Arrow premieres Wednesday, October 5 on The CW with the 100th episode likely coming in late November or early December. The series also stars David Ramsey as John Diggle, Willa Holland as Thea Queen, Emily Bett Rickards as Felicity Smoak, John Barrowman as Malcom Merlyn, with Paul Blackthorne as Detective Lance. It is executive produced by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg and Sarah Schechter.
