Objection, Spoilers! Amber Heard Witness Gives Away 'Aquaman 2' Plot Details in Court

The blockbuster Depp v Heard trial has had a lot of dramatic and bizarre moments so far, but if you are an Aquaman fan and you keep track of the legal battle – you might have had the upcoming sequel ruined for you.

It seems that one of Amber Heard 's witnesses, entertainment industry consultant Kathryn Arnold accidentally let some plot details slip as she was reflecting on how the abuse allegations affected the actress' career.

While Arnold clarified that she has never read the script of the movie and only recalled what Heard told her, she still appeared to give up the extent to which Heard's role was scaled down.

"I believe that in the first act of the movie, she was injured somehow, or it had something to do with a baby," Arnold said, apparently referring to a child that Aquaman and Mera share in the comics. She then went on to say that Mera "ends up in the hospital early in this new 'Aquaman 2 ' movie and doesn't really come out until the end to kind of wrap things up."

According to the testimony, Heard's character initially had a big action scene and a lot of interactions with Momoa before Mera's screen time was cut amid the ongoing legal squabble between Heard and her ex-husband Johnny Depp.

Arnold also claimed that Heard "trained 5 hours a day for several months with the trainer to do this big action sequence", which ended up being axed from the movie – something that the crew never disclosed to the actress before she arrived on set.

"So [her role] was radically reduced from what it was in the script and what she even trained for while she was preparing for the movie," said Arnold.

Earlier, Heard's agent said that Warner Bros. mulled the possibility of recasting Heard due to "lack of chemistry" with Jason Momoa. However, the actress' legal team believes the real reason was Heard's domestic abuse drama with Johnny Depp.
