The highly anticipated sequel '28 Years Later,' directed by Danny Boyle, has made headlines by being filmed entirely on the iPhone 15 Pro Max, showcasing the smartphone's advanced filming capabilities. This innovative choice reflects a broader trend in the film industry towards utilizing mobile technology for filmmaking, allowing for greater flexibility and creative options. Principal production took place over the summer with the use of specialized adapters and an aluminum cage to enhance the filming process. The film, with a budget of $75 million, marks a significant evolution in production techniques, especially considering Boyle's previous work with lower-resolution camcorders. Cillian Murphy returns to star in this continuation of the iconic '28 Days Later' franchise, which is set to be the first of a new trilogy. As technology advances, '28 Years Later' may pave the way for future films to adopt similar smartphone-based production methods.
