"There was this beautiful fireball that was going up," Eckhart explained. "And I wanted to do a [Michael] Jordan through the fireball." He explained to the cameraman what he was hoping to make happen and everyone got ready.
"I went, slipped, fell seven feet onto my head, and my arm just goes crack," said Eckhart -- but he didn't stop the scene. Instead, he picked up the heavy object that was part of the scene and gritted through it.
