Yes, The Matrix was always conceived as a trilogy. Specifically, the Wachowskis originally pitched a prequel (showing the machines’ war with humanity) and a sequel (showing the downfall of The Matrix).
Here’s the thing. The prequel, it’ll never happen. We’ll have to be happy with The Second Renaissance. But the sequel… I’m pretty sure if you give me Reloaded and Revolutions and a knife, I can cut you a lone, 100-minute Matrix sequel that would flatten your balls.
Maybe I’ll go do that now.
