*SPOILERS* Birds of Prey film plot leak *SPOILERS*

I was surprised when the film started with an animated version of Harley's backstory instead, as I was fully expecting the Marilyn Monroe opening that had been described, but the singing came later in the film and was only briefly shown.

I didn't see any deleted footage of Jared Leto in the film (the only shots we got of him were from Suicide Squad and you can't even really see him much in them).

I was also (thankfully) spared seeing Roman scratching/damaging his face in a rage (which was something else I had prepared myself for seeing, since he did enjoy having people's faces peeled off). He just ends up deciding to wear the mask for the film's climax. 

One thing I was glad ended up being true was that Bruce the hyena, although thought dead, turned out to be alive at the end. Considering the things that weren't in the movie, I was worried that might've been changed.

Although the film's climax did involve Harley confronting Roman as he held Cassandra Cain prisoner at Gotham Pier, the mask he was wearing didn't in fact get burned into his face. Instead, Cass reveals to Harley she took her 'ring' (referring to the pin in one of the grenades from Harley's weapon stash) and has hidden the grenade on Roman, who desperately tries to find it before he's shoved over the pier and explodes before hitting the water. 

There was nothing about the diamond being revealed to contain a nude statue of Roman all along.
