Apart from todays news on Zeta Jones The New York Times has also reported what they believe is Bond 20’s plot:
“a villain holds the world ransom with some “green house” weapon”
Also they listed some filming locations including Alaska, Ireland, England and Washington. All of which we’ve heard before. We know that Alaska comes from The Mirror’s rumours last year with Edward Woodward. We also know that the Washington rumour comes from earlier speculation of Bill Clinton’s role in Bond 20. Ireland of course comes from Pierce Brosnan’s comments on wanting to film some of Bond 20 there. And England, finally, is just obvious.
Though perhaps nothing we didn’t already know it’s still Bond 20 news.
