We must admit, the first trailer of Tenet left us scratching our heads. While it was obvious that Christopher Nolan was in his element, the trailer did leave us wondering what the hell was going on. However, the second Tenet trailer has provided some context to the imagery. The legendary filmmaker is back to testing the work of time (if you have forgotten, he played with the element of time in Inception) with Tenet and the new trailer teases how.
