Are there any zombie movies that show the complete beginning of the outbreak?

...I know a lot of zombie movies show a little bit of the beginning, but it usually ends up with the person getting knocked out (or something else) and then they cut to a couple days after...(Dawn of the Dead, Shawn of the Dead) WWZ showed a bit of the beginning but it didn't really go into detail (like where did it start in the city/US, and how long did it take to reach Brad Pitt from when it entered the city), it only showed about 5 minutes of fasted paced action (and not really local law enforcement and military reaction). Also a lot of movies start days, weeks, or months after the beginning (28 days/weeks later, The Walking Dead)

So are there any movies about the very beginning in detail, like one's that only cover 0-24 hours after?

(Basically a movie that covers the actions of the first responders and the initial reaction in general)

If you know of any more recent than 2000 can you please post it...
