There’s something almost cheeky about the Prince Charles Cinema. Tucked in a little alley behind Leicester Square, it seems to thumb its nose at the great swathes of visitors who go to the square to spend silly money in its vast multiplexes. If you don’t want to drop $20 on a second-rate blockbuster, the slightly dilapidated but always charming Prince Charles will offer you an eclectic mix of nearly new and utterly classic films for a fraction of the price. If you’re free to go to a daytime screening, it’s even cheaper. Then there are its famous marathon screenings, where you can spend an entire weekend geeking out on John Hughes movies, or staying overnight for a Harry Potter sleepover. It’s more than a cinema, really—it’s a community center for movie geeks.
