James Cameron has another mega-sized hit on his hands, landing the "biggest box office splash in history!"

HBO, the network behind Hollywood insider comedy Entourage, has taken out a two-page splash in today's Variety "announcing" the $116,844,114 weekend box office for the series' fictional feature film Aquaman, which stars Vincent Chase (Adrian Grenier) as the underwater superhero.

While it's hard to believe that the three-day box office managed to top that of fellow superhero Spiderman's mammoth bow (despite, um, rolling blackouts in the Valley and the Westside), it's good to know the Titanic director isn't above boasting about a HUGE opening weekend, even if it is for a fictional film.

You've got to love meta-theatrical twists. Especially when they find their way into cleverly disguised trade publication advertising.
