To add context....
Reading about the production of London Fields is rather interesting, because it reveals (imo) where parts of Amber Heard's story comes from, exposes a number of her 'porkies' and reveals her character rather more than she would like.
So to summarize.
In March 2013 Ms Heard is offered the leading role as Nichola Six, in London Fields.
In April 2013 Shekhar Kapur (director of Elizabeth) quits as director because Ms Heard has been hired,
Her agency, Media Talent, (who are partly financing the film) insist that Ms Heard remain in the leading role.
Media Talent secure another of their client's Matthew Cullen to be the director (Mr Cullen has experience is making adverts and music videos: and has never directed a full length flick).
Amber Heard has signed and agreed her contract relating to nudity - apparently with the proviso that she has a veto over how this is used in the final edit (which apparently she does agree, then doesn't due to Johnny (see below)).
Mr Cullen has agreed to stick to the script, written by Roberta Hanley and Martin Amis, to deliver the film on time (15th August 2014), and that he doesn't have the final say on the final cut.
Filming begins in September 2013.
At some point (and there is dispute between Cullen and Heard as to whose idea it was) Cullen and Heard decide they will 'add' to the script by filming their own ideas; and thus improve the film.
These scenes may, or may not, involve a policewoman using her truncheon on a female 'detainee' bent over the bonnet of a Tesla.
Filming slips behind schedule.
A second film crew has to be hired to try and catch up.
The film runs into money problems.
Additional finance is found via Media Talent, but the original financiers email the potential new backers to tell them not to waste their money.
Somehow the filming is complete.
The editing gets behind schedule.
And in April 2014 Mr Cullen goes AWOL, in part to make a music video for Katie Perry.
The film isn't delivered on time.
The film company bring in someone else to edit and cut the film, producing the final edit, that they hope to distribute.
(Or words to that effect)
Now, according to Ms Heard in her testimony....
Mr Depp (he drinks and takes drugs you know) was controlling because....
He interfered with her scripts, meddled in her work as an actress, was jealous of her doing sex and nudity, thought she was having sex with cast members, thought she should play more serious roles, etc....
In her version of events of their private screening of London Fields (which apparently she had Ok'd with the production company: mucky bits and all) Mr Depp became aggressive (he drinks and takes drugs you know) when he saw the sex scenes and nudity: and violently attacked Ms Heard in a fit of jealous rage. So furious did 'his monster' become (he drinks and takes drugs you know) that he wouldn't accept poor Amber had been hoodwinked; nor her further explanation (as her battered body came round from a near dear experience, that she later recounted was not that dissimilar to the film Cocoon) that the film had used a body double.... can you believe it!?.... but not satisfied with beating up his devoted and loving girlfriend, Mr Depp (he drinks and takes drugs you know) decided to further express his misogyny by sending an expletive laden email to his agent, the wilting Tracy Jacobs - who immediately had a fit of the vapours, and flushed so brightly that an assitant had to cool her brow by fanning her gently with her wig - and the email was strongly worded due to Steve (despite drinking and taking drugs) having nearly forty years in the film business, and knowing the way actors, actresses and Lassie (who was terribly misgendered) were exploited.
However, I would suggest a different scenario.....
(Keep in mind this is Amber's directorial debut) Slim didn't tell Johnny that she had signed the nudity clauses, Slim didn't tell Johnny she had changed the script. And when having seen the film, Mr Depp (he drinks and takes drugs you know) didn't appreciate Slim's directorial debut, as a great contribution to the cinematic art: but instead considered that she had been exploited. Challenged, Slim told a fib: by gasligtighting (objection foundation... over-ruled) that she didn't know that poor innocent actresses needed a contract to get their lotties out.... And that something must be done. They should immediately write to the producers and have the offending scenes removed at once.... in fact, not only Slim and Johnny.... but also all the cast members.... and they write to Mr Amis (that staunch feminist).... and in fact anyone who would listen.... for this was Harvey Weinstein MKII.... and the more fuss Slim could drum up, the less likely anyone was, to go look at her contract, or her bank account (for apparently she had indeed been paid for the nudity as per the contract) and thus find the truth.
Besides, it wasn't her job.
She took this charade to such extremes that she got the film pulled from the Toronto film festival (sealing her #metoo credentials before #metoo), refused to promote it, slagged it off and the people involved with it, and generally made a nuisance of herself: whilst rising to the pinnacle of anonymity amongst cinema-goers everywhere, and the pinnacle of adulation on Twitter among the billion-genders-crowd tthen flooding over from Tumbler (during the crack down on *cough* dubious sexual images *cough*)
Eventually the film company Nichola Six sued her for $10m (she apparently counter sued for the use of a body double in her directorial art-house debut), a legal action which was ended in September 2018, and curiously spanned much of the 13 months between the divorce settlement and her being sued for defamation by Mr Depp.
Thus, I would suggest....
That she is telling an untruth about the real reason she couldn't pay the charity money.
She is fabricating claims of Mr Depp's controlling behaviour, to hide the lie that she concealed about the contract; and like Lady McBeth it is as easy to go on as be honest.
She is inflating one of her gaslighting sessions (during the screening of London Fields) (along the lines of I didn't punch you, I hit you) into an untrue account of assault.
Oh and she is demonstrating her use of the Big Lie: in a way Geobbals would envy.
