Mexican film industry used matte paintings and miniature tricks since the 40´s. The miniature and model works were usually under the art directors and the name of the model makers and miniature artists remains unknown.
I have found only one matte painter credited at Mexican films, Max de Vega. He was a Mexican artist who worked also at
mattes at T.C. FOX matte department under Fred Sersen. I guess he went back to USA from
time to time painting mattes at some films. Mexico
During middle 40, matte painter Irving Block went to
after working at 20th Century Fox, and he set up a FX department. He
went back to Mexico
to work at MGM. USA
At some of those films there were some Mexican FX technician credited. But I don’t know if any of those artists were involved on the matte paintings. Probably there must be any Mexican art director or scenic artist who executed those matte paintings from time to time.
