LC and I went to see this on Tuesday in glorious two-dee. It was a lot of fun.
The film is one part an affectionate parody of a Roger Moore-era James Bond film, and one part a standalone spy film. It features Colin Firth as the gentleman spy "Galahad" (or Harry) versus Samuel L. Jackson as the criminal genius Valentine Richmond. Plus Mark Hamill making a rare screen appearance, Michael Caine as "Arthur", and a bunch of other people (obviously).
It was an awful lot of fun, provided you don't try and take it too seriously. Anyway, I very much enjoyed it.
