* [[Alejandro Rey]] as '''Carlos Ramirez''', a local casino owner and playboy. His reputation makes him an unlikely philanthropist, but after seeing Sister Bertrille flying alongside his plane while on a date with a beautiful woman, he feels that he has had a 'religious experience' and asks the pilot to turn the plane around so he can immediately donate his land to the convent for a new school. He is often swept, usually against his will, into Sister Bertrille's zany schemes, which she concocts with alarming frequency. Rey also appeared in a dual role in two episodes as Carlos's mild-mannered, inventive but naive cousin '''Luis Ramirez'''.
