Johnny Depp allegedly swallowed 8 ecstasy pills before finger-slicing incident with Amber Heard

Johnny Depp was reportedly high on MDMA while filming Pirates of the Carribean, with one drug-binge culminating in a violent incident with then-wife Amber Heard, according to testimony from his recent UK High Court case. 

Per The Hollywood Reporter, Depp swallowed eight ecstasy pills while working on Pirates of the Caribbean: Dead Men Tell No Tales in Australia, before embarking on what the entertainment magazine described as "a campaign of terror aimed at Heard". 

Depp ended up having the tip of his finger sliced off - which he claimed happened when Heard threw a bottle of alcohol at him - and being flown back to Los Angeles for surgery. 

Production of the Disney film was forced to shut down for two weeks, costing the studio US$350,000 a day, according to THR

Depp recently lost his libel suit against UK tabloid The Sun, which labelled him as a "wife beater" in an article regarding domestic abuse allegations made by Heard. 

The trial was littered with references to Depp's substance abuse, citing cocaine, alcohol, Xanax, Adderall, Roxicodone and magic mushrooms, as well as ecstasy use.
