As per several sites, of course the most obvious being Wikipedia, Danny Boyle has announced (never you mind about it being reported 3 months ago) that after finishing his current project, "Sunshine" , he will be immediately moving on to the third chapter in his seminal zombie saga with "28 Months Later"
Being a licensed zombologist*, I have to say that while I wasn't quite as keen on 28 Days Later as most people were (though I can't claim to really dislike it either), its sequel 28 Weeks Later is unequivacally the best serious** zombie movie ever made. And before the flames start, I should remind you that I had sex with your sister last Tuesday, and she totally agrees with me on that one. That, and that your mom knows where her lipstick has been disappearing to.....you know what I mean...
* - Zombology > n. The study of Undead human animate remains, which is usually hampered by the sheer fun of saying this field of studies name over and over repeatedly whilst doing whippets.
