While Apple Dumpling Gang would make for a wonderful remake, Disney should never touch Darby O'Gill and the Little People.
In Ireland there are still tales of leprechauns and pots of gold but this film is already the "gold" standard of the story it is telling.
Darby O'Gill features a young Sean Connery who falls in love with Darby's daughter played by Janet Munro. Connery is the new caretaker of the land but there is another local baddy that wants the job and will do anything to keep Connery out of the picture.
O'Gill enlists the help of King Brian the king of the Leprechauns who happens to be friends with O'Gill to stave off the challenger and of course, nothing really goes the way O'Gill plans it to because King Brian plays his own games and will not willingly be a matchmaker for O'Gill's daughter.
The film, released in 1959 still holds up well as a fun fantastical Irish story that takes place across the countryside of Ireland. There is no reason to remake something so perfectly done.
