Stephen Amell used his Facebook page to snuff the speculation, which started when word spread that other DC Comics heroes would first make cameos in the Dark Knight/Man of Steel mash-up (starring Ben Affleck and Henry Cavill and swooping into theaters May 2016) before populating a Justice League movie (targeted for May ’17).
The Arrow “crossover” theory then amplified when Amell himself teased “big things” to be revealed at the San Diego Comic-Con later this month.
“I appreciate all the support and enthusiasm, but not everything I post is a cryptic indicator that I’m going to be in Batman V Superman. I’m not going to be in Batman V Superman,” Amell wrote. “The next time that I either do a video or an interview with a journalist that I like, I’ll be happy to explain why this is the case. Short form: It’s not a barometer on ability or the quality of genre…. Everything here boils down to logistics.”
Amell then enthused that “playing Arrow on television isn’t a consolation prize. We play the definitive versions of our characters in the DC Universe.”
