Hi,
"El Umbrácle", name of a park in Barcelona, was a Spanish production directed by Pére Portabella in 1970. Mr Lee plays himself and is the only actor in it. Unless I am totally mistaken, the film was only released in Spanish speaking Countries and maybe it was shown on TV with subtitles. An English version on VHS is not available nor is a DVD. I have checked all the Spanish Video Shops on the web and was unable to find a copy.

The second film, again same Director. The correct title is "Vampire-Cuadecuc", that is a documentary on the making of "El Conde Dracula". Same as the first title, very difficult to find.
