This is hardly known and Emilio Ruiz got no credit for his work.
Special thanks to my friend Domingo Lizcano for this information.
The maestro painted parts of 'Tombstone' on a thin aluminum sheet.
This sheet was placed precisely in the foreground in front of the camera for
a perfect illusion of a big City.
The painted aluminium sheet of Maestro Ruiz perfectly inserted into the real scene on location.
They shot this 'DOC' scene near 'Mini Hollywood', Tabernas (Almeria).
