The trailer begins with a car bomb exploding. As the clip goes backwards we discover that the scene takes place in the middle of a tranquil Paris. Ending with a characteristic “Tick Tock” sound the trailer is designed to intrigue the viewer to watch the series and find out more about the character behind the bomb – Carlos – the terrorist who threatened the world.

The agency and Canal+ wanted to pitch the right tone, a suitably sober approach across all media, to avoid controversy and to avoid falling into the trap of eulogising a character that is after all a murderer.
