Not sure how we’ve missed this one for so long! George Romero’s third movie in the “Dead” series, Day of the Dead, features the lovable (kinda) zombie Bub.
In the movie the insane Doctor Logan, working in a military facility, experiments with Bub. He teaches him how to listen to music, shave and – for reasons – how to handle and fire automatic weapons. He even teaches Bub to talk… well, mimic… sorta. He also feeds him pieces of people. Dead ones, but still: he feeds him people.
In the huge, unexpected, out-of-nowhere-at-all surprise ending Bub escapes and uses automatic weapons! Bub, here’s to you, buddy!
