Aged Well - Like Vintage Port
27 September 2008 | by (United Kingdom) – See all my reviews

I hadn't seen this for ages. Then it was given away free with the Daily Mail.It really has aged well. The plot is still believable. Just substitute Islamic terrorists for Russian ones. Caine was brilliant and doing his 'laser' style acting in all the close ups. Something he doesn't bother with in his many pot boilers. I have to agree with some of the other posters. It really should have been promoted as Harry Palmer's midlife crisis. He would have developed just like this. The hero in the book reads like an ex-Para version of Freddie Forsythe. Caine makes the role his own and adds his own interpretation. Another of my favourites Pierce Brosnan acts his heart out too, as the stone killer Petrofsky. The Ian Richardson and Anton Rogers scene has to be a career best for both of them. Only a side plot but absolutely brilliant.
