The democratization of filmmaking technology makes it possible to do what only Hollywood was able to do just a decade or 2 ago. A few smartphones, drones, and laptops can produce big-budget special effects. It's exciting to see what stories are told when people create and distribute content directly instead of going through the Hollywood filter.

Nine teenage boys in the Nigerian city of Kaduna started experimenting with making sci-fi films in 2016.

They borrowed smartphones from family members, and made tripods out of wood.

Three years later, their first short film became a sensation, drawing the attention of millions of people, including Hollywood Stars.

The BBC’s Damilola Oduolowu met the young film-makers in Nigeria to hear their story.
