My first thought was that I agree with moussemaker - that there might be a different person on the cover of the UK edition, because I have never heard of this guy, nor any of the TV stuff he's been in. I wasn't even aware of him as a film actor.
On the other hand, the cover shot is interesting, and the ploy might be to introduce him (and his expanding film career) to a new audience in the UK, using the concept of 'Tom Hanks' as the hook for people to get a hold on what this guy might be about. I don't mind learning about someone new.
But I still haven't got my subscription copy of the Africa issue, so it could be a long time in coming. I suspect someone at the postal service has 'donated' the issue to themselves.
