The joke on the Bond 25 set is the script’s under wraps. And the response is: ‘What script?’

The screenplay for the untitled film is being endlessly re-written by a committee consisting of director Cary Joji Fukunaga, Phoebe Waller-Bridge and 007 himself, Daniel Craig.

‘She’s writing a re-write of a re-write,’ a film-making source told me of Waller-Bridge’s recent involvement in the project.

‘Daniel’s writing. Cary’s writing. The crew reckon they’re working on a well-polished s*** show.

‘They have an outline of plot, but dialogue is all last-minute. It’s not the way to make a movie. I would imagine they’ll sort it out in the cutting room. That’s where most movies get made anyway. But you’d think the Bond lot would be more together.’

The cast, led by Craig, Naomie Harris, Lea Seydoux, Lashana Lynch and Ana de Armas, have been on location in Jamaica but are heading back to Europe to link up with Rami Malek, Ralph Fiennes and Ben Whishaw.

Bond 25 has been beset with production problems.

Original director Danny Boyle left by mutual consent, after proposing to kill off 007.

Boyle was replaced by Fukunaga, who installed Scott Z. Burns to re-jig a script by Neal Purvis and Robert Wade.

Craig felt more improvements were needed, and enticed Fleabag and Killing Eve superstar Waller-Bridge to give the piece another polish.

It’s likely to be Craig’s last Bond, so it’s ironic, then, that in Bond 25, 007 is forced out of retirement and back into active service.

The reluctant Bond...playing a reluctant Bond.
