Don't know if anyone seen this yet, I just happen to see a TV SP from 8/25 on the behind the scene making of OP anime.
It shows how the anime was made and also show the new voice-over for the HD remake episodes (Arlong saga)
There is also a short part on Z. IT shows some of the main character's designs in color included 3 costumes for Luffy. As well as some radom brief cuts from movie in which some of the are not yet seen in trailer (I think)
It's not much and the source quality isn't great, but I cut out that segment and upload it.
So check it for what it's worth..
Oh and the guest VA for Ain and Binzu are crazy famous. Ain is none other than Shinohara Ryoko, a former idol who is now one of Japan's top drama actress. and Binzu is Kagawa Teruyuki a famed stage and movie actor who often appears in Taiga drama.
