Suicide Squad: The Unseen Scenes
The trailers showed many scenes, most of which never made it to the final movie. Most of the scenes were of Harley Quinn and The Joker and their flashback scenes. Jared Leto, regarding on where he went during the second half of the movie, said, "I have no idea. I think he probably went and had a drink or something. Stretched – once you get blown up in a helicopter your muscles get a little tight.”
After being asked if he was upset that his scenes were cut, he said, “Were there any that didn’t get cut? I’m asking you, were there any that didn’t get cut? There were so many scenes that got cut from the movie, I couldn’t even start,” He then went on to say, “If I die anytime soon, it’s probably likely that it’ll surface somewhere. That’s the good news about the death of an actor is all that stuff seems to come out.”
However, Margot Robbie said,
“They probably realised that the emotional through-line of the story had to be the mission that we were on, and explaining the Enchantress’ position and all that kind of stuff.
She then went on to say,
"And the [Harley and Joker] backstory stuff, though it’s magic and some of the stuff we shot was insane, they are flashbacks...so there’s a lot, but it just didn’t make sense to confuse the present story line to incorporate all that.”
