Just days before the start of Martin Luther King Jr.'s annual day of rememberance, it was revealed that the feature film honoring the man behind the "I have a dream" speech has hit a major roadblock.

The biopic's director and screenwriter, Oliver Stone, announced on Twitter via Variety.com that he has officially parted ways with the film, a brainchild of DreamWorks and Warner Bros. According to the 67-year-old Oscar-winning filmmaker, the split was due to creative differences with the studios. "Sad news. My MLK project involvement has ended," Stone posted on Twitter Friday, adding, "I did an extensive rewrite of the script, but the producers won't go with it."

According to Stone, famous for his work on the films "Born on the Fourth of July" and "Platoon," among others, the Martin Luther King Jr. biopic was set to feature details that certain individuals felt were potentially damaging to the deceased Civil Rights Movement leader's reputation. "The script dealt with issues of adultery, conflicts within the movement, and King's spiritual transformation into a higher, more radical being," said Stone. "I'm told the estate and the 'respectable' black community that guard King's reputation won't approve it. They suffocate the man and the truth."

Despite his decision to part ways with the film, Stone did share his support for King. "Martin, I grieve for you. You are still an inspiration for your fellow Americans -- but, thank God, not a saint."

Entertainment Weekly reported Saturday that Warner Bros. has declined to comment on the news of Stone's departure.

According to a previous report from Variety in October, the film was set to star actor Jamie Foxx as Martin Luther King Jr. The feature, currently listed as an untitled biopic, has reportedly been in the works since 2009.
