Nicolas Cage loves comic books so much, he created one of his own.

The actor and his 16-year-old son, Weston, took their new comic book, "Voodoo Child," to the pop culture expo Comic-Con on Sunday.

Weston dreamt up the main character, Gabriel, a biracial teenage ghost who fights the evil of bigotry in post-Katrina New Orleans.

"He's specifically dealing with racism," said Cage, a lifelong comic-book collector who played Marvel superhero Johnny Blaze in the movie "Ghost Rider" this year.

The 43-year-old Cage made no secret of his cinematic aspirations for his new comic creation.

"I have very high hopes to push 'Voodoo Child' into script and production ... and perhaps play a role in the movie," he said. "We have those ideas in motion."

Weston said he would like to play a villain in the film.

Cage said that Weston inspires him and that they hope to collaborate on other comic-book ideas. The six-book "Voodoo Child" series is published by Virgin Comics. The first issue was released this month.

"This is a highlight in my life," Cage said, "that I got to create something with my son."
