In March 2007, Boyle announced plans to create a third chapter of the film franchise, which will be given the title 28 Months Later with a 2009 release date,[34] thus creating a trilogy. Boyle has stated that his thoughts are to set the movie in Russia.[35]
In June 2007, it was announced that if DVD sales of the film did well Fox Atomic would consider producing the third film.[36]
In July 2007, while promoting the film Sunshine, Boyle revealed that he has a story formulating for the next film "There is an idea for the next one, something which would move [the story] on. I've got to think about it, whether it's right or not." Boyle also revealed that he would return as the director.[37] Alex Garland might be considered in writing the story with Boyle, but no announcements have been made.
