'Green Lantern' Villain Says His Greatest Fear Was A Single Word

"Green Lantern" readers expect Peter Sarsgaard to be at least a little eccentric when he appears in the Martin Campbell film next year as villain Hector Hammond. At least some of those quirks may come from his verbal grappling offstage, though, which included an extra-challenging vocabulary word.

"I actually did hang with this biologist from Tulane that was I think just the most eccentric guy they could find. He was entertaining," Sarsgaard told MTV News. "And he and I actually worked on my lecture that I give in ['Green Lantern'], which I kept royally f---ing up because — what was it I had said — 'prokaryotic cells.'"

The veteran actor from "Jarhead" and "Flightplan" ultimately needed a little help from an extra to finally nail the line, though he admitted that the struggle may have ended with an unintentionally nuanced pronunciation.

"I still can't remember how to say that," he explained. "Every time I'd get to it I'd just go, 'pro, pro pro,' and then an extra said to me, 'You know how you remember it? You're for Kary winning. You're pro-karyotic.'"

As for his character, Skarsgaard promised to deliver plenty of craziness to go around — and in multiple layers.

"He's got shades of gray," the actor said. "It's eccentricity on top of eccentricity."
