Both movie involve man with big muscle. Both main lead had been through up and down, hard training, big strong man with sweet soft heart.

Both movies about the main male lead were not happy in the big city. At the beginning was reluctant to go to the country side. The under privilege children ended up was the driving force to attract the teacher. Really good and heartwarming movies. Must watch

Althought one is music the other one is sport related, both main male lead have a loving soft heart for the under privilege children. It is amazing they bond together both good time and bad time

Similarity,
1) Older Woman/Younger Man
2) Smart and Successful female lead
3) My Favorite ( Song Hye Kyo )
4) Nice and Smart Male lead
5) Photography
6) Melodrama

Just like Sky Castle, in Melancholia, parents - rich parents are involved in lobbying for their kids to get admission in high universities by pressuring them to study under strict schedule, special classes and take extra courses.

And just like SC, poor are also trying their best to get in line, but are treated poorly and the genius children of poor class, suffers at the hand of school injustice, corruption and is belittle and looked down upon by rich kids.

Both movies depict the love stories of a couple where one person has dementia and their significant others don't.
