La loba (1965 Mexico)
"La loba" is a curiosity in Mexican cinema and perhaps the only
motion picture this film industry ever dedicated to a she-wolf.
It was written by Costa Rican Ramón Obón, the man behind Fernando
Méndez's classic "El vampiro", and played by a cast of prestigious
performers. The problems start when a physician (Joaquín Cordero)
arrives at the farm of a senior colleague (José Elías Moreno), to
ask for the hand of his daughter (Kitty de Hoyos), not knowing that
she turns into a she-wolf with the full moon. This is not all: the
film reserves a few more surprises for the viewer. It is interesting
that the title character, when transformed, is played by an acrobat,
and apparently the movie included a nude scene by De Hoyos, one of
the pioneers of female nudity in commercial Mexican cinema...
