I’ll be honest I wouldn’t be surprised if there is a link, as its almost exactly 10 years between them both. My thoughts are, there is at low end. The same company could be at play for the sleep sharing device and the “glove” which creates time inversion. On the other end (wild side) of the scale, I do wonder if Cobe’s children from Inception could feature in Tenet?
I will be signing up to watch this in the Manchester IMAX cinema, likely at midnight or a very late showing to avoid as many people as possible. While wearing a mask in the dark.
