How was this opening title sequence from Atkinson's Maigret made?

I've recently become fixed on how superbly the opening titles for Maigret (starring Rowan Atkinson) has been made and edited:

Would Rowan have had to have acted this out? As in, recorded a 5-6 second shot of him turning slightly so the camera can zoom into him, or is this all done using CGI or similar?

I can't tell.

(Excuse me, my visual effects knowledge is limited I do admit).

It's also possible they used a similar multiple-camera setup invented for the Matrix movies.

Imagine a curved frame with a couple of dozen micro-cameras mounted pointing inward, arcing from the above-left of his head to in front of his neck, timed by computer to take simultaneous (or almost simultaneous) images of his upper body in front of a greenscreen. Then all those images are keyed out, taken into editing software, digitally frame-blended to create that few seconds of footage, and color-adjusted to eliminate nearly all the light.
