Stiller sends himself up brilliantly, portraying himself as an egotistical, power-mad actor turned director. Superb stuff.
Gervais is his simpering best as the struggling extra trying to coax a few lines out of a film's genocide witness and expert, Goran, and the film's producer. This is a cue for classic Gervais tragicomedy. You genuinely feel for the character of Andy Millman, an individual far removed from the self confident David Brent, as he slips into Larry David territory, i.e. speaking first, thinking afterwards.
The delightfully beautiful Ashley Jensen is a wonderful actress and lights up every scene she appears in.
This episode of "Extras" is a beautifully crafted show and a joy to watch.
