Oscar-winning director James Cameron is no stranger to CGI. With movies like Avatar under his belt, you’d expect Cameron to find a particular sort of enjoyment in special effects-heavy movies like James Wan's Aquaman. But Cameron—who directed the fictional version of Aquaman featuring fictional movie star Vinnie Chase in the very real HBO series Entourage—has a little trouble with suspension of disbelief.

In a recent interview with Yahoo!, Cameron said that while he did enjoy Aquaman, he would never have been able to direct the movie itself because of its lack of realism.

"I think it’s great fun,” Cameron said. “I never could have made that film, because it requires this kind of total dreamlike disconnection from any sense of physics or reality. People just kind of zoom around underwater, because they propel themselves mentally, I guess, I don’t know. But it’s cool! You buy it on its own terms.”

"I’ve spent thousands of hours underwater," the Titanic director went on to say. "While I can enjoy that film, I don’t resonate with it because it doesn’t look real.”

While Aquaman was shot on a soundstage, Cameron will be employing state-of-the-art technology that will allow him to actually be underwater while shooting underwater scenes for his upcoming Avatar sequels.
