The stage was lit in such a way that, by standing in one place, Brad was completely invisible. All he had to do for the shot was rock forward on his legs so that his entire face appeared in the light, say, "Hello, Atrus," and then lean back again, into the shadows, where he completely disappeared. Because it was such a quick shot, we kept the camera rolling as Brad repeatedly leaned in, said the line, leaned out, and then leaned back in again two seconds later to try the line in a different way. He'd done this about four times, changing his delivery each time, when-having just delivered the line with this giddy manaical laugh-he slips back into the shadows to reappear almost instantly with this pained look on his face and a tear rolling down his cheek. No one was expecting that tear! I mean, we'd just seen him, literally one second earlier, laughing like a gleeful little kid at Christmas time! The director yells, "Cut!" and we all burst out talking about how fast that tear had appeared--and on the exactly perfect cheek, too! And Brad hears us and smiles; shrugs his shoulders, and says, "Well, that's what they teach you in acting class." I knew right then he was going to be excellent in Myst III.
