The lack of diversity in front of the camera (and behind) continues to plague Hollywood - and the latest box office hit "The Martian" is in the crossfire.

Adapted from Andy Weir's wildly popular self-published book of the same name, director Ridley Scott's big screen version cast white actress Mackenzie Davis to star as the character Mindy Park, who is a Korean-American scientist in the original book.

“This insulting practice of white-washing has got to stop,” said Aki Aleong, President of the Media Action Network for Asian Americans, an organization that follows the issue. “Alarmingly, it has been increasing in frequency.”

As Deadline notes, the "white-washing" trend still continues with the upcoming "Dr. Strange," as Tilda Swinton has been cast to portray “The Ancient One,” described as a Tibetan man in the comic book series.

Last year Emma Stone played a half Hawaiian/Chinese character in "Aloha."

"The Martian" director Scott was accused of "white-washing" last year, too, in the 2014 biblical epic "Exodus: Gods and Kings"-- the story that follows the exodus of the Hebrews from Egypt as led by Moses. With a cast that featured Christian Bale, Aaron Paul and Sigourney Weaver, the film was slammed for relegating actors of color to playing roles as servants while white actors played leads. Scott defended the casting as necessary for big budget studio approval.

It's yet another example of what Best Actress Primetime Emmy winner Viola Davis, the first black actress to receive the honor, recently described during her acceptance speech as the lack of "opportunity" for people of color in show business.
