Has it been confirmed or (please god) denied that Jar Jar Binks will appear in the new Star Wars films?
I think it’s unlikely he will appear… as a character, that is.
In an interview with Vanity Fair, JJ Abrams mused the possibility of a return for Jar Jar:
Given that Abrams clearly understands the general ill-feeling towards Jar Jar, and was willing to suggest this to a journalist, I think he’s unlikely to do an about-face and bring him back as a character in the film.
Of course, that doesn’t preclude him appearing further down the road, after Abrams has left the franchise, but it becomes steadily more unlikely. I don’t think it will happen.
Update, 8 December 2015: at a Star Wars press event, Lucasfilm president Kathleen Kennedy confirmed that Jar-Jar is not appearing:
Whilst I have not read any article concerning Episode VII featuring any mention of Jar Jar Binks he definitely is alive at the time the Emperor and Darth Vader are killed but well I'm not sure how long Gunguns live he would probably be pretty old if he is still alive though considering the mass hatred the character received I doubt JJ Abrams would consider including him in the film if he did it would be a subtle reference probably background reference but as Jar Jar has no meeting with Luke Skywalker and he is going to be in the film I see no reason for Jar Jar to appear.
His Wookieepedia entry for the Galactic Civil War era simply says,
The only thing you can do is wait and see if he appears at all in the movie but considering he has nothing to do with the original trilogy whose principle characters are supposed to play a vital role in creating the New Republic Jar Jar a known associate of Palpatine (whether he agreed with him or not) is unlikely to involve himself in anything to do with any new characters linked with the principle characters but we'll see.
