Everyone could do with a little extra science today, if only to distract themselves from the blank and empty yawn that is a Sunday afternoon. To celebrate their 125th anniversary, National Geographic is hosting a free-for-all interview with James Cameron, Robert Ballard, Jane Goodall and "explorers in the field on every continent." You can join the conversation here; explorers will be taking questions for the next hour.

Last month, James Cameron was asked for an official response to the long-debated claim that Jack and Rose could have both survived the Titanic tragedy if Rose had just scooched over a bit.

In a recent interview with IGN, Titanic director James Cameron was asked to respond to the longstanding myth that Jack and Rose could have both survived if they had just shared the raft.

Relax — it sounds more exciting than it is. But hey, it's still pretty cool. A 2004 photograph released to the public this week shows a coat and boots sunken in the mud near the Titanic's stern. Based on the way the clothing items are "laid out," there is good evidence this was once a person, says James Delgado, director of maritime heritage at the National Oceanic and Atmosphere Administration.

A $17.4 million weekend gross for Titanic isn't exactly sad — but it's a little disappointing, given that at one point, Titanic was the highest grossing film of all time. James Cameron's 3D conversion could not compete with The Hunger Games, which once again took the top box-office spot, this time with $33.5 million. The film's current domestic gross is now more than $300 million.

Today, Titanic 3D docks in theaters. Here's a supercut of almost 50 instances of Leonardo DiCaprio's (unfortunately?) immortal line, "I'm the king of the world," popping up throughout pop culture since the movie's original 1997 release. The phrase might be the most obnoxious thing you can say on a boat and otherwise. Sometimes the people making the reference note this. Sometimes, tragically, they do not.

Director and deep-sea explorer James Cameron is all set for the 3D re-release of Titanic. Other than the 3D conversion, Cameron left the film alone — except for one minor fix.

Director and science nerd James Cameron is making an attempt to travel to the Mariana Trench, the deepest part of the ocean. The last time someone tried this was in 1960, when Swiss oceanographer Jacques Piccard and Navy Lt. Don Walsh spent a weak 20 minutes at the bottom. Cameron plans on filming and exploring for six hours down in the trench, which is a staggering seven miles below sea level.

Titanic director and Explorer-in-Residence of the National Geographic Society James Cameron recently constructed a 43-inch-wide "capsule" that he climbed into, then had dropped to the bottom of a five-mile-deep trench off the coast of Papua New Guinea. His next goal is to get dropped into a seven-mile-deep trench, so he can look at the creepy deep sea animals that live down there. So, now we know James Cameron isn't claustrophobic, aquaphobic, ichthyophobic, or nyctophobic.

The little lady's got some heat on her, fresh off of one hit and onto a potential second one. Also today: Tom Cruise likes 'em big, two actors join the fight against the zombies, and J.Lo might J.Go.

We all know that actors, directors, and producers make a lot of money, but Vanity Fair crunched the numbers and tried to figure out just how much cash everyone brought in last year. Their grosses are a little gross.

Britney Spears overshadows the bride at a wedding. Claire Danes flies coach, and won't stop bragging about it. Charlie Sheen's rehab will take three months. David Arquette is done with rehab. Monday gossip is momentous.

Here's a trailer for the James Cameron-produced Australian thriller Sanctum, about a group of daredevil cave explorers who get stuck way under ground after a flood (or something). It looks like your typical cheesy disaster movie.

Remember Avatar, the giant space adventure about how to hair-rape wild animals? Well, hopefully you want more of it, because that's what James Cameron has just agreed to direct, Avatars 2 & 3. Sadly, this means no Cameron-directed Cleopatra.

And it's gonna be a big one. Also today: Some TV show announcements that will please both nerds and gays, and nerdy gays. The Muppets meet some friends. And the world's sexiest director lands another sexy project.

Attack of the Show's sit-down chats are usually populated with C-level celebrities and the semi-stars of genre television, but Kevin Pereira shocked the world on Monday by delivering an in-depth interview with directorial superstar James Cameron.

Around 300 protesters from Amazon tribes, armed with bows and arrows, have occupied a hydroelectric plant that is being built on an ancient burial site, and demand talks with the government. There have been no James Cameron sightings yet. [BBC]

Before his humble blue-hued space opera, poor James Cameron was rattling a tin cup around, dancing for nickels to buy sweet, sweet sangawiches. But now he's rich as a king! The director stands to make nearly half-a-billion bones from Avatar.

Avatar… biggest movie EVER. That 3D stuff sure was impressive! And now the franchise is moving into a new genre, with the fall 2010 release of Hustler's This Ain't Avatar XXX, a sexxxy adaptation of the James Cameron hit. [Slashfilm]

Avatar and Titanic director James Cameron is shocked that the "morons" at BP rejected his offer to show them how to solve the oil spill. He directed a movie about a maritime crisis, once, why wouldn't they want his wisdom?
