As we suspected , Interview with Lee Smith explains he couldn’t work on Tenet because of scheduling.
https://www.ibc.org/production/craft-le ... ?adredir=1Smith is not doing Nolan’s next film, Tenet, which is currently being shot with Jennifer Lame (Hereditary) in the cutting room. This was simply a matter of scheduling which clashed with 1917.
“When you are presented with a film that is happening, greenlit and ready to go right now then I think you should say yes rather than wait for a director you also want to work with but whose film is waiting to be financed,” he explains. “There’s always the risk that films can be pushed back. It might eventually put you out of sync with those you want to work with, and the decision is never taken lightly but you have to work - editors also need to get paid.”
