One big question that’s going to keep coming up as people begin to see Danny Boyleand Alex Garland‘s anticipated sequel, 28 Years Later, is about how the 2007 sequel, 28 Weeks Later, fits into the mix. After the duo’s 28 Days Laterwas a respectable worldwide hit in 2003, helping to bring zombies back into vogue long before The Walking Dead, Spanish filmmaker Juan Carlos Fresnadillo took the reins of the franchise while Boyle and Garland went on to make the sci-fi thriller, Sunshine, with Cillian Murphy. They remained on 28 Weeks Later as executive producers, and the sequel only made slightly less than the original movie.
