Dark Tower

The Dark Tower - in which a series of books Stephen King started in 1986 is continued in a movie, but a lot of people keep thinking it is all ten books crammed into 90 minutes. It's not. Idris Elba is an awesome gunslinger from this weird world where he is always versus Matthew McConaughey, who is a creepy weirdo called The Man in Black. There is this kid named Jacob in regular reality who accidentally finds a portal to the weird world, while he was being chased by some adults/bullies/henchmen. Jacob jumps into the portal because the other option is to be taken away by some scary adults, but then he meets Roland the Gunslinger and they decide to help each other. They find another portal, and they come to regular world and Roland falls in love with aspirin and Coke, but Man in Black has a ton of goons searching for them everywhere.  Man in Black wants Jacob to power his psychic machine that will destroy the Dark Tower, and therefore destroy the world. A chase ensues, Jacob gets wrecked by the machine, but Roland saves him and the Man in Black can eat it.
