This evening will be dedicated to two aspects of film restoration. On one hand the problem of sound restoration, on the other to the issue of preserving and restoring the apparatuses of film history. So. The Man Who Knew Too Much will be screened thanks to the activity of collecting and restoring sound apparatures of Jean Pierre Vercheure, who made possible the use of a Perspecta Sound system, which was the stereophonic sound system used for this film. It will be a great bet: to be able to see and hear the film as it used to be at the time of this release, with a type of sound which is now completely forgotten and which cannot be reproduced without the restored apparatuses. Then, another dream: how to reproduce the colours of Technicolor, again, a matter of machine sand tecnology which disappeared.
