A hercegnő és a kobold (The Princess and the Goblin) is a 1991 feature length animated movie based on a children's book by George MacDonald. While it was an international European collaboration, it was directed by a Hungarian director, and premiered in Hungary first. We claim it as our own.
The upside? This one totally exists with English dubs!!
(... and also the glorious moment when Kófic drop-kicks the kobold Prince into a waterfall.)
I have a lot of nostalgia for this movie. I think a lot of other '90s kids share it, especially when it comes to the main song that gets repeated multiple times. While in English it goes "All that's strong inside us / That tells us wrong from right / Becomes a song inside us / To chase away the night" in Hungarian the main chorus tells you "You don't have to be a hero / As long as you keep the light / So that it can turn to song inside you / And chase away the night." Either way, it is a very memorable song, and I am pretty sure it adds some serious bonuses to any kid's stats.
