The final scenes in the old moonshining film "THUNDER ROAD" has a car crashing into an electric substation. The script did not call for the crash (or at least not that bad a crash) and when the stuntman driver crashed (he was killed in the crash) the cameras were running and the scene was left in in the driver's memory.
I know almost nothing about Parliament (that's a brand of cigarettes, isn't it?) but changing that word to Congress would make it more meaningful. Well, maybe to us at about 3,,000 miles east west of most of you!
