So what’s the big difference between the new red band trailer for Dimension Films’ summer splatter spectacle sequel Piranha 3DD and the tamer theatrical trailer that was released almost a month ago? In the words of Chris Griffin, “BOOBIES!”

You can watch the red band trailer here below.

In addition to the bounty of bouncing boobage on display here we have David Hasselhoff in a cheeky cameo, Ving Rhames getting all Planet Terror-ed up, Gary Busey getting gnawed up by piranha guppies, and the lovely Danielle Panabaker doing a Shivers/Slither bathtub homage. The Feast team of director John Gulager and screenwriters Marcus Dunstan and Patrick Melton (with additional assistance from producer Joel Soisson) are on hand to orchestrate another glorious ballet of carnage and chesticles.

The 3D horror remake sequel Piranha 3DD was originally supposed to open last November before it was pulled from Dimension Films’ release schedule and given an unspecified 2012 premiere date, but that didn’t stop the studio from releasing a new trailer today.

You can watch it here below.

Alexandre Aja, the director of the 2010 hit Piranha 3D, has turned over his directorial duties to John Gulager this time around.

At the Spike TV 2011 Scream Awards, Piranha 3D won the award for Most Memorable Mutilation for the scene where the girl gets scalped alive by a motorboat.

To accept the award was none other than Scalped Alive By Motorboat Girl herself, a massive digitally projected talking head which arose from the pool of water on stage, who, while honored and excited to accept the award, went on to introduce the world premiere of the teaser trailer for Piranha 3D.

Iron Man was a great movie. With an unusual amount of humor and sarcastic wit, the movie took on the usually tough assignment of telling the superhero origin myth and as a result became a summer favorite with audiences. It also was a financial powerhouse, earning nearly $320 million in U.S. domestic receipts by the end of September.

With such success, a sequel is inevitable. Hollywood being Hollywood, someone will always suggest a way to “improve” a monster hit. Take the much-publicized decision to replace Terrence Howard with Don Cheadle in the sequel. While I do not think that Mr. Howard was the strongest link in the first movie, that opinion has much more to do with the fact that the character of James “Rhodey” Rhodes was a minor, supporting character in this version of the origin myth, and not any reflection on Mr. Howard’s acting chops. Yet, I’m sure that someone in Hollywood felt that Mr. Cheadle will add something more to Rhodey either being Iron Man or War Machine in the next film. People say “don’t mess with a winning formula,” but they’ve never heard that rule in Hollywood (or never listened, if they did.)

So, it is in the spirit of messing with a winning formula that I offer some further boneheaded casting changes and the rationale behind them that could be proposed by some mid-level Hollywood creative type hoping to make a mark on Tinsel Town …
