Well...not exactly but believe me she was also in black...
After waking up, the film has some flaws in modelling and wargaming terms :
- The British infantry uses grey instead of white trousers.
On the other hand the environment of those troubled days is very well pictured and filming, acting and dialogues are first class, but don´t expect to see an absolutely accurate war/historical movie.
The fortifications of the Linhas de Torres are pretty well done, at least to my knowledge, and possibly there was a good contribution from the experts of municipality of Torres Vedras itself, as it was the city who ordered the movie in the first place for the 200th anniversary of the event.
