VIDEO : 'Avengers: Infinity War' Writers Dish On The Soul Stone

The secret of the Soul Stone was kept hidden for 18 movies.
The stone was mentioned but no details about its location have been revealed.
ComicBook.com says the film's writers wanted to tease the stone's location until Infinity War.
In fact, it's only in Infinity War that we learn Gamora knows the stone's location.
The stone was on a distant planet not mentioned in any previous Marvel movie.
---We didn't want it to be random either. Like it's on Planet X. Which happens to have lots of, you know spiders on it. That would be difficult.---
