28 Days Later2002

[Major West takes Jim to an enclosed yard in the mansion while showing him around]

Major West:
And lastly, meet Mailer. [Mailer charges out at them but is held back by a chain; Major West casually introduces them to each other.] Mailer, Jim. Jim, Mailer. Got infected two days ago. Mitchell managed to knock him out cold, and we got a chain around his neck.

Jim:
You're keeping him alive?

Major West:
The idea was to learn more about infection. Have him teach me.

Jim:
And... has he? [Mailer completely ignores several open but untouched cans of food left out for him]

Major West:
In a way. [he kneels near Mailer, inducing a fit of groaning and thrashing] He's telling me he'll never bake bread, plant crops, raise livestock. He's telling me he's futureless. And eventually, he'll tell me how long the infected take to starve to death.
