If it's time to have movies in the vein of brotherly love like those Jutathep Kun Chai siblings, then I would like to once again see Got with James Ji. They acted as a good doctor team in Kun Chai Puttipatt. I think it's also about time to have another movie of brotherly or sisterly relationships like those old movies Seven Brides for Seven Brothers, and Little Women.
Although I prefer grand happy plots but if you need to have a sweeping story of loyalty and great love between 2 brothers it would have to be "Of Mice & Men". It's from a novel.
That film, John is a gentle giant elder brother with the mind of a child, and Gary the younger sibling who always protect him. John is so loving that when he hugs a puppy because he loved it so much, he innocently killed it. Because of that his brother took him around the country to escape prejudice from every place they have tried to settled in. John is very strong & so they found manual jobs easily. Until John again unintentionally strangled a girl, and this time the stakes are different. It has a very powerful ending! I imagined James Ji would be perfect as the innocent giant, and Got the one who loves him.
