Kim Libreri, an award-winning visual effects artist based in Northern California, has worked on movies including Artificial Intelligence and War of the Planet of the Apes.

For nine years he has been working with a piece of technology better known for computer games, in particular the smash-hit Fortnite.

The Unreal Engine, owned by Epic Games, provides the building blocks and tools that a computer game developer needs, but is increasingly an attractive technology for TV and film producers.

The latest version of technology, Unreal Engine 5, is coming out next year, and Epic has been heavily trailing its features.

It should allow visual effects artists like Mr Libreri to slot graphics and images straight into a scene, with little fuss.

"With traditional filmmaking, a director and cinematographer might shoot a scene on set -then down the line, hand footage and creative direction off to a team of virtual reality artists and designers, who enhance that material with visual effects and computer-generated imagery in a separate phase of production, says Mr Libreri, who is now chief technology officer at Epic Games.

With Unreal Engine collaboration between the director, cinematographer, production designer and virtual reality teams can occur simultaneously as an interactive process on set.

"Unreal Engine 5 promises to further free the artistic process by making it easier to take virtual worlds developed for feature film and television, and run them in the game engine in real time," says Mr Libreri.

Anthony Hunt, is the chief executive of Cinesite, a multinational digital entertainment group, whose visual effects film work includes blockbusters such as Avengers: Endgame, Independence Day: Resurgence, Iron Man 3 and more.
