'Twilight: Eclipse': Taylor Lautner wore wolf 'Teletubby' suit; Kristen Stewart pet him

"Twilight's" Taylor Lautner has gone to many lengths to help make the franchise seem realistic in its portrayal.

We've already heard how the 18-year-old packed on the pounds and lived at the gym to bulk up for "New Moon," and USA Today reports the next step he took for wolfy versimilitude: Putting on a suit to play his animal alter ego.

Most of the wolf scenes were put in after the fact, using computer graphics, but it's still important that the performances seem real, especially when Bella (Kristen Stewart) scratches the wolf version of Jacob behind the ear.

"There is dialogue and I talk to him," Stewart says. "I said, 'How am I going to do this without Taylor?' " Instead of having to use her imagination to interact with the CG wolf, Lautner volunteered to act as its stand-in.

"That day I came on set and put on this tight gray spandex suit," he explains. "Basically, it looked like a Teletubby. I had this circle on the face but everything else was covered. It was weird. But, yeah, I stood there and would literally bend over."

Stewart chimes in, "I would actually pet his head."

Aww, that's so sweet (and hilarious). Although he says the suit was gray spandex, we can't help but imagine him in a full wolf costume, or perhaps a costume like Max wore in "Where the Wild Things Are."

Lautner gets wofly in "Eclipse," in theaters on June 30.
