Johnny Depp is being sued for allegedly assaulting a crew member on 'City of Lies'

In his legal documents, the crew member slammed the 'Pirates of the Caribbean' star over his conduct, alleging he "was intentional and malicious and done for the purpose of causing plaintiff to suffer humiliation."

And he claimed Johnny's "intoxication and temper created a hostile, abusive and unsafe work environment," which eventually resulted in him being assaulted by Johnny during filming of the crime thriller.

Gregg claimed he was eventually fired from the movie when he refused to sign a release waiving his right to sue over the incident.

His attorney, Arbella Azizian, said in a statement: "My client wants to make sure Mr. Depp is held accountable for his conduct on set so that, in the future, others will not be put in the same situation."

When reports of an alleged altercation were first raised earlier this year, director Brad Furman defended Johnny and praised the actor as a "consummate professional".

He said in a statement: "Johnny Depp is a consummate professional, great collaborator and a supporter of other artists.

"He always treats the crew and people around him with the utmost respect.

"Movies can be stressful, and non-events often become exaggerated. We all love stories -- there isn't one here."

'City of Lies' - a drama focused on the investigation of Notorious B.I.G. and Tupac Shakur's murders which also stars Forest Whitaker - is expected to be released in September 2018.
