Director: JJ Abrams
Writers: JJ Abrams and Lawrence Kasdan rewrote a script by Michael Arndt. based on characters created by George Lucas. Possibly using George Lucas's original story treatments for episodes 7, 8 and 9 written back in the 1980s.
sure, Lucas sucks. but I am not at all sold on JJ Abrams as a writer OR director. look at his credents. not at all impressive. he is a really bad version of Spielberg. Kasdan is an obvious iconic and sentimental choice, but re-capturing "magic" after, what, 30 years is going to be tough. and his credits since Star Wars/Indiana Jones are not all that impressive either -- although he did write (or co-write) the game Shadows of the Empire, which I loved as a kid.
Michael Arndt, on the other hand, is at the top of his game RIGHT NOW. I am really curious as to why he's no longer with the project and what the "re-write" actually means. Did they keep his story? Did they change everything? Whose story is it, etc.
I was a HUGE Star Wars fan growing up, so when Brad Bird (fantastic) was originally rumoured to direct the (rumoured) Arndt-written project, I was so excited. Now I am totally skeptical, myself.
Honestly, I am more curious about potential sideproject movies that go off the main story path. The best thing about SW is how there are so many great secondary characters and stories. I would love to see some animated (or live action) films about Yoda, the Mos Eisley Cantina crowd, Jabba, etc. Seems like every SW nerd has their personal favourite secondary characters. I always liked Greedo.
