Depp is suing The Sun newspaper which accused him of being "a wife beater".
On the third day of his libel action against NGN, publishers of The Sun, and the newspaper's executive editor Dan Wootton, Pirates Of The Caribbean star Depp, 57, dubbed his ex-wife's claims of a drug-fuelled three-day ordeal of assaults as "pedestrian fiction".
The case is shining a light on the tempestuous relationship between Depp and Heard (34) who married in Los Angeles in February 2015. Days later she sought a restraining order against Depp and the court was shown pictures of Heard with a bruise on the cheek. The divorce was finalized in 2017.
Heard is attending the three-week trial and is scheduled to testify next week. "It is like Dr Jekyll and Mr Hyde. I wish you nothing but good". "And on the Friday you had a cigarette in your right hand, as you do most of the time, and you threatened to put it out on your face". "Physically and emotionally from the things you say and did while (messed) up", she wrote.
He says Ms Heard's claims are a hoax and part of a dossier she had been collecting as "an insurance policy".
Depp has acknowledged heavy drinking and drug use, but said Heard's claim that drugs and alcohol made him a "monster" was "delusional".
The Sun's defence relies on a total of 14 allegations by Heard of Depp's violence between 2013 and 2016, in settings including his private island in the Bahamas, a rented house in Australia and a private jet.
The lawyer said Depp was "in an uncontrollable rage" and "screaming you were going to kill her".
Depp denied assaulting Heard or being out of control on the plane.
Wass claimed Depp found the incident "hilarious", and remarked, "I haven't laughed so hard in years".
"There were blackouts for sure and in any blackouts there are snippets of memory", he said. But he insisted "I am certainly not a violent person, especially with women".
Mr Depp also admitted "accidentally" headbutting Ms Heard while she was said to have been "flailing and punching" him at their Los Angeles penthouse in December 2015.
"I was convinced that it was either Ms". Heard and furthermore I have never hit Ms. The couple allegedly had a fight after Miss Heard found out Depp was having an affair. He denies ever hitting her. He said he'd had it altered from "Winona Forever" after he split up with actress Winona Ryder years earlier.
"I have no mercy, no fear and not an ounce of emotion, or what I once thought was love for this gold digging, low level, dime a dozen, mushy, pointless dangling overused flappy fish market", said the text, read by Wass.
By June 2016, however, Depp said he had become "quite bitter" because he felt he was being publicly depicted as "a wife beater".
Depp said Heard threw two vodka bottles at him, the second of which "severed my finger and crushed my bones".
He slapped Heard across the face, pushed her against the fridge and smashed her head against it, and she barricaded herself in her bedroom to escape him, the court was told. As the row escalated, they called a friend of Heard's whom Depp alleged was responsible.
Wass said Depp "wound up like a baseball pitcher" and threw it at his wife at one of their mansions while one of Heard's friends was on the other line.
In a text message to his doctor after the Australia altercation, Depp called Heard "malicious, evil and vindictive" and said she was "desperate" for fame, adding "that is probably why I was acquired".
Near the end of his testimony, Depp was asked by his lawyer, David Sherborne, about medical notes from August 2014 that referred to Heard's "history of substance abuse", including an addiction to cocaine.
When Wass said Heard often had two or three glasses of wine during an evening, Depp shot back: "Two or three bottles".
Depp agreed with the lawyer that the house was "wrecked" after the couple's argument.
