Watch Fire and Ice: The Rocket Richard Riot (2000) Official Trailer

In 1955, as a hotly contested hockey season was coming to an end, the star of the Montreal Canadiens, Maurice "the Rocket" Richard, was suspended for attacking an opponent with a stick and hitting a referee by then president of the NHL Clarence Campbell. This set off a huge riot in the streets of Montreal. The documentary claims, unconvincingly, that this event added to the sparks of the political revolution in Quebec that led to the rise of the separatist movement.
