Soy un Héroe (2016)

Both Are Japanese And Based On Zombie Apocalypse.

Both Main Leads Are A Male Who Don't Want Give Up. And Try Their Best To Protect Others.

Both movies are about zombie apocalypse, so the plot is very similar. But the atmosphere in this two movies are very different. Train to Busan is more like a tragedy-drama movie than a horror movie, while I am a Hero is an intense horror-zombie movie with a very few drama. I am a Hero has more violence, blood, and gore than Train in Busan.

The vampire and zombie are similar since they can't talk, I got a similar feeling while watching them.
