Love that character, so memorable for such a minor part.
But I think he talks much more like Gollum, and the Gollum voice was minted by Peter Woodthorpe in 1978 (And in a good part by Wolfe Morris in 1968) both long before ST3 and Yoda (Not to mention the books from 1937 and 1954).

I hope JJ doesn't just do homages to scenes like the Cantina but I do hope that the characters hang out in some dangerous places and not boring senate chambers.
