I think Franny Armstrong's McLibel film is way beyond "inspirational".
The protagonists, without being lawyers, gave me one of those New Respect for the "Rule of Law" feelings. The libel action brought by McDonald's against two pamphleteers was made into the longest court case in centuries of British history. They were (are) like the Rachel Carson of socio/economic examinations of the modern version of raw power.
The propaganda power of Murrow's Harvest of Shame 1960 telecast is rivaled in this.
Would that we had persevered as well in the Air Pirates case.
