(WCWF) -- It's the end of an era for sure, as prep has begun for the final episode of Arrow. Executive producer Marc Guggenheim took to Twitter giving us this inside look.
Meanwhile, Arrow's Stephen Amell shares his appreciation of working with The Flash's Grant Gustin, making a super hero team come to life as they wrap up their time together in the Arrowverse. But it doesn't stop there...
In a video on Instagram, Amell thanked everyone involved in Crisis on Infinite Earths, as the filming of the crossover has come to an end.
A tearful goodbye... he finishes by saying, "I think that it's probably the coolest Comic Book thing that's ever been on TV... and that makes my heart happy."
Arrow's Rick Gonzalez also tweeted from the set of Crisis on Infinite Earths, saying its so much fun when the extended family/universe connects.
