'Cut!' - the AI director

Media captionAI technologies from IBM and Microsoft were used to make the video

From Ex Machina to Terminator, artificial intelligence has long been a subject for film-makers. But what if AI could actually make a movie?

At the Cannes Lions advertising festival on Thursday morning, an audience was shown a series of short films in the annual New Directors Showcase, which highlights emerging talent.

One of the entries had AI as a director.

It has long been the most secretive of Britain's intelligence agencies - but, lately, GCHQ has been tiptoeing ever so carefully out of the shadows.

Last month, the signals intelligence operation opened a Twitter account - "Hello World," was its first offering - and last night its director spoke for an hour at an event where he even took questions from members of the public.

I've just acquired a whole new identity. It comes in the form of a plastic card with a chip in it, and it means that I am now a resident of Estonia. Or rather an e-resident, because this card is a symbol of Estonia's bold ambition - to export its expertise in digital identity to the wider world.

The e-Residency programme, which has already attracted 10,000 people from around the world, offers anyone who pays 100 Euros some of the benefits of the digital ID cards which Estonia's 1.3 million citizens have had for more than a decade.

It was the deal that was supposed to be the final stage in the reshaping of Britain's mobile phone market. But now the O2/Three marriage has been blocked by Brussels, where does that leave phone users?

Better off, according to regulators. The UK's communications regulator Ofcom, in particular, had argued that allowing the number of players in the market to fall from four to three would inevitably lead to higher prices, poorer service or both.
