There was much fanboy rejoicing when is was learned that Lawrence Kasdan was on board to write a new 'Star Wars' spin-off movie and consult on 'Star Wars Episode 7.' After all, this is the man who wrote 'The Empire Strikes Back,' a movie that isn't just the best 'Star Wars' movie, but one of the best science fiction movies ever made. Although the full details of whatever Kasdan is working on (a Yoda movie? Young Han Solo?) are buried in an underground bunker somewhere, he recently spoke about his involvement in the new films.
