Scarlett Johansson is experiencing backlash and opposition for her film roles choices once again, but she has defended her decision to portray a transgender man in her upcoming movie.

According to industry media outlets, the performer, popular and famous for her role as Black Widow in 'Marvel's Avengers' movie franchise, is set to star in 'Rub & Tug', a film which is based on the colorful life of Pittsburgh crime boss Dante Gill in the 1970s and its climax and thrill.

To the surprise, Johansson will also serve as a producer on the film.

The casting quickly ignited a wave of disapproval online and on social media world. Many filmmakers criticized for not hiring a trans actor to star and decry the project as another instance of Hollywood sidelining an underrepresented group.

Following are some of the comments and tweets showing up regarding this hot topic

When approached for comment on the backlash, a Johansson representative told online to the magazine Bustle "Tell them that they can be directed to Jeffrey Tambor, Jared Leto and Felicity Huffman's reps for comment."

Tambor, Leto and Huffman are cisgender actors who have earned fame and awards for portraying and representing trans characters onscreen (in the Amazon series 'Transparent' and the films 'Dallas Buyers Club' and 'TransAmerica', respectively).

Canadian director Jean-Marc Vallée, who directed and guided Leto in his Oscar-winning role in Dallas Buyers Club, said he is not in favor with the opposition.

He said from Montreal on Wednesday,"[It] doesn't mean that because I am casting this type of role that I need to go to this type of person. This is the nature of acting.'

Moreover, Vallée said he's open to seeing transgender actors at auditions, but "it's not about aiming for ... an astronaut because your character is an astronaut."

Ghost in the Shell reunion

However, Rub & Tug will reunite Johansson with Rupert Sanders, who directed her in the controversial and conflicting live-action variation and adaptation of Ghost in the Shell.

That project came under fire because Johansson played a character that — in the famed original manga series — was a Japanese woman.

Thus, it really portrays the idea that she always opted for the controversial and not-so-easy characters for films and movies and always defended herself!
