Minicraft?

Where did the idea of the iron golem from minecraft come from? Because I think I've seen it in some film.

The second line from the Minecraft Wiki says it right.

The iron golem is inspired by a movie. The film was called "The Castle in Heaven".

The fact that the golem drops a rose when he dies is also an allusion to this film.

Laputa: The castle in the sky

by Studio Ghibli

And that he gives a rose to baby village camps is the greatest allusion

There are also normal villagers. But it's pretty rare.
