Ayn Rand was furious when she heard that Howard Roark's speech at the trial was being trimmed, chiefly because it was considered long, rambling and confusing, especially to Gary Cooper who didn't understand it. She got the studio to make sure that the speech was untouched and in its entirety in the finished product.
