In early cuts, the movie's opening detailed
June Moone's posession by Enchantress in real time. Reshoots
reshuffled the scene to be later in the movie in flashback form in
favor of a new opening centered on Deadshot.
Deadshot in the prison cell, watching the rain fall and thinking
about his daughter.
El Diablo observing the flame of a lit match, before putting it out
due to his vow to no longer use his powers.
El Diablo being escorted to a training center by being placed in a
tube that fills with water to quel his flames, and then
unceremoniously dropped onto the ground.
Early interviews mentioned Captain Boomerang's racism and sexism,
but the movie is light on examples of such behavior, which have
apparently been deleted. Most of them were reportedly directed at
Katana, to whom Boomerang is attracted to.
Early reports indicated more backstory for Killer Croc, revealing
that he lived his entire life as a social outcast due to his
physical deformities and has convinced himself that he is beautiful
in his own way. Croc crossed paths with Batman while working as
muscle-for-hire for numerous Gotham's crime bosses, while secretly
planning to take over one day. There were also scenes displaying
his affinity for making sculptures out of discarded materials.
Aside from jokes about Croc viewing himself as 'beautiful,' one of
these were retained in the final cut.
Also deleted was a scene where he (Croc) becomes sick at the
helicopter escort to Midway City, throws up half-digested pieces of
goat, and then eats them again, disgusting the nearby Navy
Seals.
Early cuts reportedly included a passing reference to Slipknot
being serial rapist, likely to further paint him as unsympathetic
to the audience ahead of his own death.
More scenes of Rick Flag and June Moone's romantic relationship,
including him reading the files of the Suicide Squad recruits after
Waller delivers them to him.
Another scene where Flag and Moone are out on a date.
Extended scene of Joker interrogating Captain Griggs, including the
line, "I can't wait to show you my toys," which was in every
trailer, but was removed from the movie.
Joker and his men escaping after shooting up a restaurant. Harley,
who is already affiliated with the Joker, follows them on a
motorcycle and intercepts their car. Joker bangs his head against
the glass in frustration.
Joker and Harley then get into a fight, which ends with Harley
pointing a gun at Joker's head. Joker sweet-talks Harley into
lowering the gun, charming her, then backhands her across the face.
Afterwards he sweet-talks her again and they kiss.
Extended Ace Chemicals scene where Harley jumps into the chemicals.
More bits of dialogue by the Joker.
Extended Batmobile chase scene with more interaction between Joker
and Harley. One of the examples, presented in all the trailers, is
the Joker punching the roof of his car.
Harley using her baseball bat as a mock gun to play shoot at
invisible foes.
Extended scene of Joker breaking into the nanobomb manufacture
facility to arrange for Harley's neck-bomb to be disabled.
More interactions between Harley and Boomerang. Early cuts
apparently included her really disliking him despite growing
affectionate to all other members of the squad.
Extended bar scene with Harley taking everyone's orders. Deadshot
calls for a shot, Katana wants whiskey, Croc and Boomerang settle
for beer, Harley asks Diablo wants and he prefers water which she
jokes, is "a good idea." The scene was featured in the trailers,
but in the movie it cuts directly to Deadshot's speech about them
almost pulling the mission off.
Removed several scenes with the Joker to repaint his relationship
with Harley as more loving rather than abusive.
Joker and Harley get into an argument after he rescues her in the
hijacked helicopter. In early cuts he reportedly pushes her out to
kill her, then the helicopter gets shot down. This was apparently
reworked into the helicopter getting shot down first and Joker
pushing her out to save her.
Joker returns during the final battle in the subway station, face
half-burnt from the helicopter crash, which apparently leads to a
brief altercation with the Suicide Squad. He calls for Harley to
escape with him but she refuses for once in order to help her
friends, and the Joker escapes after throwing a live grenade at the
group to cover his own escape.
