Arrow Star Stephen Amell Talks DC Crossovers, Constantine Cameo

Last week, Stephen Amell, the star of the CW series Arrow, posted on Twitter that he would be willing to guest star on Constantine should NBC choose to revive it. But apparently, there had already been talks about a crossover!

If you missed it, here's what Amell posted on Twitter on Friday:

#SaveConstantine -- Hey TV Networks / Netflix and the like... If you pick up the show, I'll guest star.

Amell followed that up with "Can't wait. Constantine & Queen want to get sh*t done. Let's make it happen. #Constantine." Whether that happens or not remains to be seen.

At Wizard World Comic Con in Philadelphia over the weekend, Amell spoke about crossovers in the DC TV universe, even among shows on different networks.

"There is an opportunity for interconnectivity with any DC television show that exists. Like, as an example, yesterday Constantine was cancelled. And there is…yeah, I know, it’s brutal…it’s a good show, and it should come back. And it may come back, like there are various platforms where it could come back,” Amell said, according to ComicBook.com.

“Now, Constantine was an NBC show. I’m on The CW. I had had discussions with DC… so not NBC, not CW… but with DC Entertainment about guest starring on Constantine when it was still on the air. And that was and is still on the table. So we have Flash, we have Legends of Tomorrow, a new show which is directly connected to the Arrow universe, we have Supergirl… I’m sure it’s going to be amazing… there’s Gotham obviously, and I’m missing something… Titans, there you go... we have no shortage of options for me and other characters to populate.”

But how exactly would the crossover work? Amell explained the logic behind it.

“The reason that I was going to guest star on Constantine, at least the idea that we were throwing around was he’s an expert when it comes to the Lazarus Pit, which is now something that is a part of and will continue to be a part of Arrow,” he said.
