Which film provided the initial proof point demonstrating that consumers and exhibitors valued the authenticated audio performance of THX?

Answer

Return of the Jedi

The system achieved its first significant validation through its association with the release of the film *Return of the Jedi* in 1983. The successful implementation and exhibition of this major motion picture using the newly established THX standards served as a crucial proof point. This event demonstrated tangibly that there was a significant appetite among both the general public (consumers) and theater owners (exhibitors) for a consistently high, authenticated level of audio quality when experiencing films.
