This is possibly the most important zombie movie that never made it to production. The story behind Romero's Resident Evil movie is that Constantin Film was considering George Romero as a director for the first-ever Resident Evil movie adaptation. Romero completed a draft of the screenplay but was turned down by Capcom. Instead, Paul W.S. Anderson got the job and the final product became Resident Evil starring Milla Jovovich, released in 2002.
This is one of those moments where you wish you could take a peek into an alternate reality and see what Romero could have done with the franchise and what possibilities that could have come to be. But you never know, since the screenplay is done, maybe Romero's estate and Capcom can do something with it, if let us say, Twilight of the Dead or Queens of the Dead is successful.
This documentary does a deep dive into the who, why and when's of Romero's Resident Evil, with new documents and interviews with key people in the industry and all that jazz. Also, the original voice actor of Wesker, Pablo Kuntz, is doing the narration.
