Hells yeah.. watched Deliverance recently too... Love this quote from the Wiki page;
The film is infamous for cutting costs by not insuring the production and having the actors do their own stunts (most notably, Jon Voight climbed the cliff himself). In one scene, the stunt coordinator decided that a scene showing a canoe with a dummy of Burt Reynolds in it looked phony; he said it looked "like a canoe with a dummy in it". Reynolds requested to have the scene re-shot with himself in the canoe rather than the dummy. After shooting the scene, Reynolds, coughing up river water and nursing a broken coccyx, asked how the scene looked. The director responded, "like a canoe with a dummy in it."
