It’s been 23 years since the world was introduced to Danny Boyle’s genre-defining horror film 28 Days Later. The film helped reinvigorate the zombie horror genre by introducing the so-called “fast zombies” to the horror lexicon.

It was a divisive change of pace, so to speak, within the zombie genre fandom. Some welcomed the change since it brought a new type of energy to what had become a stale, oft-ridiculed zombie film trope of the slow, shambling undead. The purists saw it as separate from the rules introduced by the zombie subgenre’s godfather, George A. Romero, with his Living Dead films. Yet, it doesn’t matter which side of the debate someone was on (something even I have fallen into spending way too much time with) there was no denying the fact that Boyle made a great horror film…no, let me correct that. He made a great film.

This was followed 5 years later by 28 Weeks Later (minus the involvement of the first film’s director and screenwriter, Danny Boyle and Alex Garland) with Spanish filmmaker Juan Carlos Fresnadillo. While not on the same level as the first film, it did add something new to the world created with the first film. It even had a mid-credit sequence that gave a hint as to how the series could move forward.

The latest “Song of the Day” comes courtesy of the series film composer John Murphy. He did the soundtrack for the the first film and the sequel. The song I picked was used in the first film, but took center stage in the sequel. The piece of music is the track titled “In the House – In a Heartbeat” that becomes the main theme for 28 Weeks Later.
