They recently returned to Berlin to resume filming for the highly anticipated Matrix 4.

And Keanu Reeves and the cast of the sci-fi thriller enjoyed a celebratory July 4 meal in the German capital on Saturday night

The actor, 55, was joined by his girlfriend Alexandra Grant, 47, and Carrie-Anne Moss, 52, who starred as Trinity alongside Keanu in the previous three films of the series.

Neil Patrick Harris was also spotted later on as the cast met at a private apartment in the edgy Kreuzberg district.

Keanu cut a low-key figure in a smart suit and shirt, while his long hair and beard look a world away from the clean cut Neo of the first film in 1999.

His philanthropist girlfriend was similarly suited and booted for the get-together in a dark jacket with white detailing on the arms.

The Matrix 4 will be released in 2021 and production began in early January with Lana Wachowski returning as co-writing and director, and while filming stopped in Berlin in March the stars returned to Berlin last month.

When the new movie was announced, Lana said in a statement: ‘Many of the ideas Lilly and I explored 20 years ago about our reality are even more relevant now…

‘I’m very happy to have these characters back in my life and grateful for another chance to work with my brilliant friends.’

Aleksandar Hemon and David Mitchell co-wrote the Matrix 4 script alongside Wachowski. Keanu is again playing Neo with Carrie-Ann back as well.

Reeves’ next film is the next Bill And Ted’s Excellent Adventure with Alex Winter.

Ever since Reeves and Grant went public with their relationship in November, there has been much speculation about when their romance.

Some publications said they had been together for only a few months but in June, Jennifer Tilly told Page Six that they had been an item for ‘years.’

Grant is an artist and philanthropist. Born in Ohio, she has been working in the arts since graduating from Swarthmore College in 1994 with a BA in history and studio art.

The artist is known for her use of language and exchanges with writers as a source for imagery in her sculpture, painting, drawing, and video works.

The talented artist fostered her love for the spoken word as a child, after growing up around the world, living in Mexico, Spain and France.

She has exhibited at prestigious spaces around the world including Los Angeles County Museum of Art (LACMA), Galerie Gradiva in Paris and The Harris Lieberman Gallery in New York.

In 2008, Alexandra founded the philanthropic grantLOVE project which produces and sells original artworks and editions to benefit artist projects and arts non-profits.

Alexandra and Keanu have a history that goes back years, first collaborating together on a grown-up’s picture book, Ode to Happiness, in 2011.

The book was a success, sparking the poet-artist duo to create their second book together, Shadows, in 2016, with Grant photographing Reeves while he was filming John Wick.

Since then, the two have been spotted together at art galleries, book signings, posed for Vogue Spain and even traveled to Germany to work together.

Speaking of working together on their second book, Grant told W Magazine: ‘We can spend a lot of time debating. Like, A raspberry hue? And should it be darker? We can get obsessive.’

Shadows is compiled of dark silhouette images of Reeves taken by Grant and poetry written by the Matrix actor.

Grant told the LA Times of her collaborator: ‘No one can move the way he can. He’s a really extreme performer. That’s a huge piece of why those images are so interesting…

‘I knew that if I moved the camera as we danced together, as photographer and subject, we could create these wonderful optical illusions.’

The two founded publishing company X Artists’ Books in 2017, with a focus on ‘unusual collaborations’ and books that ‘don’t really have a place because they’re between genres’.
