Frustration with an all-white main cast in "Exodus: Gods and Kings" was voiced earlier this week in the hashtag campaign, #BoycottExodusMovie....

This is not the first time that biblical films have been criticized for "whitewashing." In an op-ed for Sojourners last year, Ryan Herring noted that his initial excitement for "Noah" and "Exodus" turned to "disdain" after realizing that "not a single one of the leading roles in either movie was given to a person of Middle Eastern descent."

"Some things never change. In Hollywood, whitewashing, also known as racebending, is one of many longstanding tradition...Historically, this practice was used to discriminate against actors, both male and female, of color," wrote Herring. "The most common examples of this in the past were white actors dressing up in what is known as blackface, redface, and yellowface. While maybe not as controversial or blatant today, the practice of whitewashing still continues in Hollywood...[where] roles from scripts that clearly call for a person of color are given to white actors."
