Of the three films released as part of DC's shared movie-verse of films, two of them have been directed by Zack Snyder. Snyder helmed both "Man of Steel" and "Batman v Superman: Dawn of Justice," while David Ayer got behind the camera for the just released "Suicide Squad." But, as Ayer revealed in a talk with Collider, Snyder did have a hand in "Suicide Squad" that extended beyond his executive producer credit.

And SPOILERS ahead for those of you that haven't seen "Suicide Squad" yet and want to remain spoiler free.

It turns out that Zack Snyder directed a scene in the movie -- the flashback scene showing how Captain Boomerang was apprehended by the Flash. The scene starts out showing a diamond heist with Captain Boomerang and his partner. He then betrays his partner, knocking him out with a thrown boomerang. The Flash -- played by Ezra Miller in full costume -- then appears, cracks a joke, and the Captain is caught.

As Ayer said: "Flash was always in the movie, we just got lucky because 'Justice League' was happening and they had the uniform, they had the assets, so we were able to get that photography."

The scene was shot in London on the "Justice League" set with Snyder behind the camera while "Suicide Squad" was in post-production.

Directed by David Ayer and starring Will Smith, Margot Robbie, Jared Leto, Viola Davis and more, "Suicide Squad" is in theaters now.
