Christopher Nolan’s “Tenet” is coming to theaters July 17th, and people are going to show up with masks, without them, and who cares. Warner Bros. is counting on that from the looks of this trailer. John David Washington and Robert Pattinson star along with Elizabeth Debicki and Michael Freakin’ Caine. The trailer looks great. Like all non-Batman Nolan movies, it’s all about the reversal of time. Watch “Memento” while you’re waiting, just to feel the rhythm. I can’t wait, personally. PS Here’s a clue: Tenet is a palindrome. The whole movie is a palindrome.
