Documentary sequels can tend to divert in focus from their predecessors, sometimes enough to become their own separate projects instead of being direct follow-ups as originally intended. Remember how Michael Moore's plans to do a Fahrenheit 9/11 sequel evolved into Capitalism: A Love Story? According to The Documentary Blog, Spike Lee's sequel to When the Levees Broke: A Requiem in Four Acts has also now gone in a slightly new direction, at least for its climax.

The new two-part doc, titled If God is Willing and Da Creek Don't Rise, does still revisit the Hurricane Katrina tragedy five years later as planned, including a look at how hard it's been for folks to return to the area, but it's also going to veer off and explore the BP oil spill, as well. Reportedly the doc, which premieres on HBO August 23rd and 24th, was supposed to conclude with the New Orleans Saints' Super Bowl victory (back in January), but Lee's crew has continued to make trips throughout the year and shot footage for the film as recent as two weeks ago.

Here is the official synopsis confirming the inclusion of the spill:
Five years after Hurricane Katrina, director Spike Lee returns to New Orleans to see how the ambitious plans to reinvent the CrescentCity are playing out in the all-new, four-hour documentary IF GOD IS WILLING AND DA CREEK DON'T RISE. He finds a patchwork of hope and heartache in a story that is book-ended by a pair of momentous events - the historic 2010 Super Bowl victory and the disastrous British Petroleum oil spill - that changed the history of America's most unique city once agai
Just as the first film (and likely the sequel) was very critical of the U.S. government's role in and response to the Katrina disaster, this second installment will surely do the same with the BP mess. Lee is quoted from an address to the Television Critics Association saying, about claims of the spill clean-up, "I don't care how many scientists BP buys, that oil did not disappear."

Will you be tuning in later this month to revisit Katrina and explore the BP disaster with Spike Lee?
