Question: **END OF MOVIE SPOILER WARNING** At the end of the film, Will Smith dramatically sacrifices himself with a grenade, just after telling Anna and Ethan to hide until dawn. However, they are currently below ground in his basement, meaning no natural light. Wouldn't this mean that any Zombies surviving the grenade would still be able to attack Ethan & Anna?

Answer: He may have installed an escape tunnel in the old coal chute. Being a virologist, he'd know the protocol of having two exits from every lab. Therefore they could have escaped out the top of the coal chute once it got bright. Also, the implication is that the main mutant was only after Robert. Once he (and Robert) was dead, they wouldn't have bothered chasing Anna.
