Avengers: Infinity War's depiction of Thanos pleased Marvel fans around the world when the blockbuster movie was released earlier this year, but there was a quibble some people had.
If Thanos (Josh Brolin) was so powerful, how come he didn't go for the Infinity Stones sooner? Why did he wait this long before finally taking action?
The answer is actually pretty straightforward and was revealed in the commentary included in the digital download release of the movie.

Directors Joe and Anthony Russo and writers Christopher Markus and Stephen McFeely provide the commentary, and they revealed that Thanos chose to wait because he had no idea about the location of the Soul Stone (via io9).
Thanos began hunting down the Infinity Stones with urgency once he heard from Nebula that Gamora knew the answer.
