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.
“You really are trying to run a single production across three different productions,” Greg Berlanti previously told Indiewire about the crossover.
Arrow premieres Wednesday, October 5 on The CW with the 100th episode likely coming in late November or early December.
It is executive produced by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg and Sarah Schechter.
