Just to add some thoughts on how Chewie looks - while J.J. hasn't seemed to have tinged his fur with any grey whatsoever to suggest he's 'aged' somewhat like his ol' sidekick Han has (and why should he?, considering Wookiees can supposedly live for hundreds of years)...the thing that struck me most about his brief appearance in the 2nd teaser, was the fact that he looked so 'well-groomed'.

But I reckon it's the fact that Chewie was just *so* straggly-looking throughout ROTJ, that I kinda still expected to see him be a little scruffy in his appearance since we last saw him all those years ago...rather than the very 'slicked-back' look he had when we first saw him in the original movie.

However, when I checked, he was a little bit more groomed again by the end celebrations of ROTJ...and it's good to see he's managed to look after himself a little better ever since. :)
