I'm not sure about his whole life, but a CGI Yoda movie of his forming "good relations" with the wookiees would be quite cool. Anything more may ruin the mystery that is part of Yoda, as Darth_Call said.
I feel the same way about Sidious' master, Plagueis. I worry that if and when that book ever gets published, it might spoil some of Palpatines' mystery.
However, as you say Mike, if it's done well - it would rock! Is it worth the risk?
Yodamentary ;D To be honest, when I saw the thread title, I thought that it was about our Master Yoda, like a biography or something!
