Jonathan Mostow is set to write and direct the adaptation of one of Marvel Comics' oldest superheroes
Sub-Mariner, says the Hollywood Reporter.
Sub-Mariner's real name is Prince Namor, a half-man/half-amphibian from the underwater kingdom of Atlantis. An anti-hero, he frequently finds himself helping the human race as much as he fights it when humans pollute the waters.
The Sub-Mariner first appeared in "Marvel Comics" #1 in 1939, when Marvel Comics was known as Timely Comics. He made his first modern appearance in the pages of "Fantastic Four" in the early 1960s.
