Back to the Future is a famous movie franchise that has become synonymous with time travel, adventure, and 1980s nostalgia. However, if you're looking for alternatives to the well-known phrase "Back to the Future," there are a few options available. "Journey in Time" or "Time Tripping" are playful ways to reference the plot of the movie series. A more literary alternative could be "Chrono-return," which utilizes the Greek root word for time. Another option might be "Retrocasting," which plays on the idea of casting back in time. Nonetheless, none of these options are quite as iconic as the original "Back to the Future".
