The actress Eva Green has made her first appearance in her High Court battle over the collapse of a multimillion-pound independent film project.

The Casino Royale star, 42, is entering the witness box on Monday afternoon in the court battle over the £4 million sci-fi film A Patriot she was due to star in, before production was shut down in October 2019.

She was pictured smiling as she arrived at the High Court in central London in a dark green velvet jacket and sunglasses shortly after 10am, surrounded by paparazzi.

Ms Green is suing the production company White Lantern Films, claiming she is entitled to her million dollar fee (approximately £810,000) for the movie, despite its cancellation.

White Lantern Films is defending the case and bringing a counterclaim against the French actress, alleging she made "unreasonable demands" and undermined the film's production.

The French actress is due to enter the witness box to give evidence in the claim on Monday afternoon, the third day of the trial in London.

At the start of the trial on Thursday, Max Mallin KC, for White Lantern, claimed that Ms Green had an "animosity" towards a vision for the film held by one of the film's executive producers, Jake Seal.

The High Court heard last week that WhatsApp messages sent by actress Eva Green calling a producer a “devious sociopath” are being used to paint her as a diva.

The barrister said that in exchanges with her agent and the film's director, Ms Green claimed Mr Seal was planning to make a "cheap B movie", describing him as "the devil" and "evil", production manager Terry Bird as a "f****** moron", and local crew members as "shitty peasants... from Hampshire".

Ms Green's barrister Edmund Cullen KC said that the legal battle was "designed to paint my client as a diva to win headlines and damage her reputation".

Mr Cullen later said that the messages "must be seen in context" of negotiations over buying the rights to the script.

Describing the film as a "passion project", Mr Cullen said the actress "bent over backwards" to make the film but "the financial plan was never going to work".
