In 1987, Firth along with other up and coming British actors such as Tim Roth, Bruce Payne and Paul McGann were dubbed the 'Brit Pack'. That same year, he appeared alongside Kenneth Branagh in the film version of J. L. Carr's A Month in the Country. Sheila Johnston observed a theme in his early works of playing those traumatised by war. Firth portrayed real-life British soldier Robert Lawrence MC in the 1988 BBC dramatisation Tumbledown. Lawrence was severely injured at the Battle of Mount Tumbledown during the Falklands War, and the film details his struggles to adjust to his disability whilst confronted with indifference from the government and the public. The film attracted controversy at the time, with criticism coming from left and right ends of the political spectrum. Firth's performance led to a Royal TV Society Best Actor Award and he was nominated for the 1989 BAFTA Television Award. In 1989, he played the title role in Miloš Forman's Valmont, based on Les Liaisons dangereuses. This was released just a year after Dangerous Liaisons and did not make a big impact in comparison. The same year, he played a paranoid, socially awkward character in Argentinian psychological thriller Apartment Zero.
