10 Small Details You Missed In Tenet
1. Ten Minutes Forward, Ten Minutes Back
As mentioned earlier, the word Tenet being a palindrome fits in well with the film's unconventional approach to entropy. In addition to this, it also acts as probably one of the most subtle spoilers in recent years.
As the film's third act kicks into high gear, Ives briefs Tenet operatives on their plan to stop Sator from activating the Algorithm and reversing the planet's entropy, destroying it in the process. The main component of the plan is a temporal pincer movement, a fictional play on a real-life maneuver that involves two separate groups of troops gathering around an enemy camp.
In this case, the movement involves both normal and inverted troops fighting Sator's men at the same time, with the normal troops relying on information from their inverted counterparts and is supposed to take place over a ten-minute timespan.
The duration of the act as well as its palindromic nature can be succinctly summed up in the film's title (ten-et/te-net). This is arguably one of the film's more inspired touches and shows how well-thought out some of its ideas were.
