Just found this over at www.darkhorizons.com which has a link to www.showbizireland.com:
Gabriel Byrne's Next: Gabriel Byrne briefly talked the third prequel to Showbiz Ireland - "They have approached me and they are talking about it but nothing is definite yet. I think the way George Lucas works is not the usual way where they have a script then they offer you a role. I think the develop characters around particular people as far as I know. They have not said anything to me about what role I would play". Byrne is currently working on David Cronenberg's "Spider" and also talks about what's next for him - "I go back to New York then finish this film in Toronto and then Christmas. Next year I have two projects, one in Australia and maybe one in London. I think that will be it for next year. I can't tell you which projects cause I haven't signed the contract so I can't". Thanks to 'Ray'
