The Valencia Life network reports... 

A film crew from the National Geographic Channel are currently in town, making a documentary on the Holy Chalice that has been venerated in Valencia since the fifteenth century. 

Some shooting has already taken place in the Museum, and last night the team shot part of the Last Supper celebratory mass in Valencia Cathedral. 

Today the cameras will be shooting various  scenes of the Holy Week processions, and also some interviews with leading experts that have been brought to Valencia such as Janice Bennett, and German Historian Michael Hessemann, both of whom are experts in the field of Holy Relics, and who participated last year in a conference in Valencia on the Chalice.
