The filmmaker said that Tim Burton's take on the property "defined" his generation, and admitted being "in love" with the franchise.
"I love Batman, I didn't grow up reading the comics but Batman movies, when that first Tim Burton Batman movie came out that kind of defined, in kind of like a weird way... the generation that I was in," he told Flickering Myth.
"That first Batman movie, in a way it defined what a blockbuster was for me, more so than any of the '70s movies.
"When that first Batman movie hit it was like this cultural volcano that defined what the superhero blockbuster was in a way that just completely drew me in as a kid."
Johnson went on to praise Christopher Nolan's more recent interpretation of the superhero, and said that he is focused on his own projects for the time being.
"Batman is definitely the one superhero movie franchise that I'm 100% just completely in love with, and I love [Christopher] Nolan's so much, man.
Warner Bros is yet to announce its future plans for the Batman franchise, but is expected to use the character in its 2015 Justice League movie.
