In the 2012 time travel movie "Looper," the main character Joe (played by Joseph Gordon-Levitt in a convincing facial prosthetic) sacrifices himself to change the future. He aims to prevent his older self (Bruce Willis) from killing a child named Cid who is destined to become future villain with unique telekinetic powers— known as The Rainmaker. In the final scene, Cid is grazed by a bullet, but younger Joe’s shoots himself to make older Joe disappear from the timeline— offering the possibility of a different timeline and future outcome for the boy. 🎥

In 1893, Ingersoll Lockwood wrote “Baron Trump's Marvellous Underground Journey”, a tale about young Baron Trump's quest to find a "world within a world." Lockwood’s second book, published in 1896, was titled “1900, Or The Last President.” 🎥

Also in “Looper”, Young Joe/JGL carves a message into his own arm, which appears as a scar on the arm of his future self, Old Joe/Bruce. To communicate a meeting location across time, he carves the name "Beatrix," who was the waitress at a roadside café he often frequented. This choice of name is likely a reference to a line from Thomas Pynchon's book “V.”, which mentions "barmaids named Beatrix" as being the "fairest and saddest." 🎥
