Rockdale's courthouse will temporarily transform into a Hollywood stage and represent one of the important legal arenas in the Civil Rights movement when the movie "Selma," comes to town.

The courthouse will be used to film scenes of Alabama federal Judge Frank Johnson's courtroom, where he ruled on cases affecting the Civil Rights movement and allowed the 1965 march in Selma, Alabama to take place.

Rockdale County Superior Court Judge Robert Mumford quipped that the director hadn't asked him to play Judge Johnson because they apparently already had "someone named Martin Sheen."

The movie, which is being co-produced by Oprah Winfrey and Brad Pitt among others, will be filming during the last week of May. Judge Mumford said he will be out of town that week for a training conference and was not due to hold court that week.

Paramount Pictures is backing the project, which will be directed by Ava DuVernay, who was the first black woman to win a Sundance Film Festival Best Director Award for her 2012 film "Middle of Nowhere," which starred David Oyelowo, who will play King in "Selma."

Deadline Hollywood, which first reported Winfrey's involvement, said "Selma" is the second MLK Jr. project Winfrey is involved with, noting her Harpo Productions company is behind a seven-part HBO miniseries "America: In the King Years."

The movie is also filming scenes in the Covington square May 20-22.
