We reported yesterday that production on the sci-fi sequel Men in Black III has been delayed. A new report today not only confirms the production hiatus, which has been extended until March 28, but reveals the real reason behind the delay.

Sony has given director Barry Sonnenfeld the extra time needs to prepare for the third act. Studio executives were impressed by the footage shot from the first act, which was completed late last year before the holiday break. It was believed that script issues were the cause of the delay, although this new report indicates original writer Etan Cohen is back on the project. Jeff Nathanson had been brought on for four weeks to tweak the script.

The delay will not have any effect on the availability of the cast and Sony is still planning on a May 25, 2012 release date for Men in Black III.

Men in Black III will alternate between present day and 1969. Will Smith is back as Agent J, who travels back in time to meet a young Agent K, played by Josh Brolin. Tommy Lee Jones will return to play Agent K in the present day.
