There were only three movies in the Marvel Cinematic Universe.
The box office competition would soon be hammered by a fourth, Thor, upon its debut on May 6, making for two worlds in which frozen undead monsters posed a threat.
George R.R. Martin drew from a number of sources for inspiration, including Norse mythology, which is one of the reasons why the Frost Giants the Asgardians battled looked so much like White Walkers, particularly the Night King, who didn't rear his creepy head until season four of GOT.
Fast-forward to 2021, there are now 23 films in the MCU, not including the pandemic-delayed Black Widow and at least 10 others in the works.
