Welsh actor, Rhys Ifans, will supposedly be joining the cast of the yet untitled Bond 23. Ifans is said to be in the film along with No Country For Old Men star, Javier Bardem. MGM has not come out with an official press statement yet confirming or denying this.
The only concrete casting so far is Daniel Craig playing Ian Fleming master spy, Dame Judi Dench playing M, with Sam Mendes Directing. Neal Purvis and Robert Wade are returning to write the screenplay for the 5th time and John Logan will be doing the "Paul Haggis script polishing" this time around.
