Keanu told ET he had already read the script.

‘It’s very ambitious,’ he said. ‘As it should be!’

Lana Wachowski will write and direct the movie, and production is set to begin in early 2020.

Lana told Variety: ‘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’
