Genndy Tartakovsky revealed that upcoming episodes of the series will feature longer segments and tie in to the upcoming theatrical feature Star Wars: Episode III.
"We're doing 12-minute episodes this time, as opposed to the three-minute episodes last time," Tartakovsky said. "It really allows us to open up both character development and action."
Cartoon Network begins airing the new episodes on March 21, 2005.

Tartakovsky added that the five new chapters will relate to information that appears in the traditional opening scroll crawl in Episode III. The shorts will also feature a new character, General Grievous, who will "be the new villain in Episode III."
