Willi Geiger, digital supervisor on Battleship, has previously worked with CG water before for Poseidon (2006), Pirates of the Caribbean: Dead Man's Chest (2006) and The Last Airbender (2010) accumulated experience in making water look real. "When I first looked at Battleship, it was pretty clear we'd have to go to the next level yet," he said. ILM revamped their entire system to accommodate the changes necessitated for the movie with so many shots dealing with the lead characters. "There were hundreds of those hero shots in this movie and that made it pretty apparent that we were going to have to do something bigger and newer for this," he said. It took many months to work on perfecting the water effects. "There's a lot of water, billions of gallons," said Geiger. "It's absolutely huge."
Grady Cofer, visual effects supervisor, a veteran of Lady in the Water (2006), Pirates of the Caribbean: Dead Man's Chest and Star Trek (2009), spoke about the advancement of CG technology in relation to water. "We walked through all of the sequences with Peter Berg, the director, and realized how much of this movie was gonna take place in the ocean and how much intricate interaction there was going to be between these ships and the water," he said. "We knew we were going to have to raise our game in terms of creating CG water."
The complexity of the simulation turned out to be quite the challenge. "We had very intricate ships that were breaching up through the surface," said Cofer. Many things are going on: ships are pulling water out of the ocean and then pouring it over the surface. "If you're trying to represent all of those collisions and you're representing water from a meshed volume to a splash, to mist and reincorporating back into the ocean, that's a very kind of complex simulation," he added.
Pablo Herman, visual effects supervisor and second unit director, has worked on many big budget movies such as Men in Black (1997), Master and Commander: The Far Side of the World (2003) and The Last Airbender. According to Herman, the key on Battleship was using plate references to ground the movie in reality as much as possible. "We started with plates that we shot on location, on the water itself, even if the water wasn't doing what it was supposed to be doing, at least we started with the right reference, the right lighting and everything else," he said.
Berg's mandate was authenticity. "He wanted real oceans, real ships at sea and so he was capturing lots of footage like that," said Cofer. The movie offered many complexities to deal with, the dynamics of how water splashes and everything representing the motions of the ships in the water. "You have to represent all of that in what you're doing in CG and so, we were really holding ourselves to the standard of reality in this movie," he said.
Glen McIntosh started as a character animator on Star Wars Episode 1: The Phantom Menace (1999) and was promoted to animation supervisor on Battleship. One of his biggest challenges was creating CG ships with some individuality to each one. The effects had to reflect how the ships were using the water as part of their characteristics. "There's certain shots where just before it's getting ready to jump and just before it's getting ready to fight, it's putting its legs out so it's the equivalent of getting angry," he said.
It was all about using water as a way to express the alien ships and imbuing them with individual characteristics. Cofer relates how Berg wanted the ships to "build up all this energy at their wing tips and slap down into the water and launch themselves into the water and splash down," he said.
For Geiger and McIntosh, the goal was to use the water effects as part of the storytelling. "You're in the service of telling the filmmaker's story and getting the filmmaker's vision up on the screen," said Geiger. After getting feedback from director Peter Berg, McIntosh said the animators began to see how much water was influencing the character of the ships. "All of a sudden they were putting more movement into different areas of the ship which would kick start the simulations so there was a lot of back and forth to sort of make these (ships) as alive as possible," said McIntosh.
The animation was refined and then sent to Geiger's department to incorporate the simulations. Cofer concurs about the breakthrough in interaction between water and the characters in the movie. "I definitely think that we kind of push the limits and are representing water in a very intricate and realistic way," he said. The artists and effects supervisors at ILM will keep pushing the envelope. "You're never done," he said. "You're always kind of progressing things and making things better."
On the Blu-ray, the special features go into details about all the hard work that went into giving life to a variety of characters and objects in the movie. Geiger hopes viewers will notice details on the Blu-ray that would have flashed by too quickly in the movie theaters. "The details that went into building some of the models is just incredible, stuff that would be very easy to miss," he said. In fact, 135 CG models were created for Battleship. Geiger mentioned the huge explosion on the deck of the Missouri as one example.
McIntosh said everybody at ILM tried to help Berg by adding a history to the designs of the aliens. "We didn't know how extensively they would be used in the close ups," he said. "If you look closely, there's scars. We looked at Gregory Peck in Moby Deck, Robert Shaw in Jaws, that weathered old-salt skin that we thought was important to sort of show that these guys have done this on other planets."
Battleship represents an important milestone in making water effects as realistic as possible on screen.
