Here's an extract from this site, on a passage about makingthe filk Deliverance - 'Summer of Deliverance' By Christopher Dickey

"I was supposed to know how to shoot a bow, one of the assistant directors asked me to shoot one of the trout they'd put in a little makeshift pond at the edge of the river. They needed a close-up miss and a close-up hit. I'd never shot a trout. But, hey, this was going to be like -- this was -- shooting fish in a barrel.

Just to get the feel of it, I took aim at one of the trout, steadied the shaft, aiming low to compensate for the refraction of light, and released. The arrow went right into it, just the way it was supposed to. Now the cameras rolled. And rolled. And rolled...and rolled. I could not hit another fish. We joked. We laughed a lot. I made excuses. The sun was going down and we were losing light. This whole little sideshow was turning into an embarrassment, then a humiliation, as people came over to see why we were taking so long. "I thought you knew how to do this?" said the assistant cameraman. Even fish in a barrel are hard to hit with an arrow. Anyone might have made an equal fool of himself.
