Marlon Brando -- Son Defends 'Last Tango' Scene ... He Did NOT Plan a Rape!

Marlon Brando's son is coming to his late father's defense, saying there's no way his father would ever have plotted to sexually violate his "Last Tango in Paris" co-star.

Marlon's oldest living son, Miko Brando, tackled the controversial confession from the film's director, Bernardo Bertolucci. A video recently surfaced of Bertolucci saying, in 2013, he and Brando planned at the last minute to use a stick of butter on Maria Schneider during the sex scene, and never gave her any forewarning.

In the vid, Bertolucci says he wanted an authentic reaction to rape ... not acting. Schneider, who died in 2011, has said no intercourse took place, but she was shocked and strongly objected to the way things went down.

Miko calls the story pure crap, and says, "That's not the human being" my father was. He has a theory about why Bertolucci ever made the comment.

Celebs like Jessica Chastain, Chris Evans, Anna Kendrick and Ava DuVernay have expressed outrage at Brando and Bertolucci for essentially plotting to rape a woman -- but Miko's just not buying it.
