28 Years Later is coming up soon, and it will forge ahead without one of its major actors. The franchise film that started it all, 28 Days Later, featured Oscar winner Cillian Murphy in one of the leading roles, playing Jim. Despite surviving the events of the first movie, Jim did not return for the 2007 sequel 28 Weeks Later. Some viewers who watched an early 28 Years Later trailer thought that Murphy may be returning to the franchise in zombie form, but this theory was later debunked.
