Anybody else seen this: George Lucas is set to make another 'Star Wars' movie after promising fans the latest instalment would be the last. The director is reportedly planning a seventh sequel of the popular sci-fi series after telling friends he wants to develop the story further. Lucas has already outlined the plot of the as-yet untitled movie, which will take place 100 years before current film 'Star Wars Episode III: Revenge of the Sith'. A movie insider said: "George believes there are even more stories to tell. "His latest idea would feature an almost all-new cast, apart from the Jedi master Yoda, who would be the hero of the new movie." Lucas's plan is sure to excite 'Star Wars' fans as the tiny green character is a cult hero among devotees. In the saga, Yoda, voiced by Frank Oz, famously trained Jedi knight Luke Skywalker to defeat evil villain Darth Vader. However, a spokesperson for the movie-maker refused to confirm the plans.
