In the 1990’ies the court thriller was a real genre. “Closed Circuit” is a bit of an updated version of that genre.
In a contemporary story we follow the events after a terrorist attack in London. One suspect is apprehended and brought to court. Two ex-lovers are assigned to defend him, but it soon becomes clear that the man is already convicted.
Crowley made a descent court thriller that becomes a bit more of an action thriller as the film goes on. The film has wel built-up tension.
Perhaps an unsurprising, but certainly descent film.
