Team Edward and Team Jacob face off in The Twilight Saga: Eclipse, the third film in the vampire series based on Stephenie Meyers' best-selling books, and they share a lot of screen time in the third installment.

After Bella (Kristen Stewart) falls for vampire Edward Cullen (Robert Pattinson) in Twilight, Edward breaks up with her in New Moon, and Jacob (Taylor Lautner) gains traction by supporting Bella in her time of need. It doesn't hurt that he's a buff werewolf who frequently shows off his glistening pecs in the rain. (Spoilers ahead!)

The third film, Eclipse, brings the love triangle to a boil in a literal three-way scene. "I loved playing with the three characters together," Stewart said. "There's literally a scene where Edward and Jacob, who are mortal enemies, are in a tent with a sleeping Bella in between them. It's a ridiculous circumstance to find yourself in."

Lautner elaborated on the situation. "Edward is forced to let me sleep in the same sleeping bag as Bella, just so she doesn't die."

In a dire situation, the undead Edward does not possess the body heat to keep his beloved from freezing to death. Werewolves, however, run a temperature of 108 degrees. "She's shivering to death, and I'm warm," Lautner continued. "I'm the only thing at that moment that can keep her alive."

Watching the two hunks fight over Bella is what the Twilight fandom is all about and is why fans have divided themselves into Team Edward and Team Jacob. Lautner and Pattinson play it up on screen.

"It's a funny scene," Lautner said. "There's a lot of ribbing going on between Jacob and Edward."

The upcoming second movie, New Moon, brings Edward and Jacob together only at the end, so the tent scene in Eclipse will really be the payoff of those tensions.

"It was weird, because I hardly did any scenes with Taylor [in New Moon]," Pattinson said. "We just did the scenes at the beginning and the scenes at the end, and he had his entire storyline develop without me being around, which is interesting, because I had no idea where his performance was going. It wasn't really a competition or anything. It was all independent. Whereas in Eclipse, we did scenes together, all the time, with Bella. It really shows the dynamic in that one."

New Moon opens Nov. 20. Eclipse is coming June 30, 2010.
