Santiago Cabrera is Aramis: Santiago Cabrera is already well established in BBC television after his Lancelot role in the hugely popular 'Merlin'. He now faces a similar sword-wielding, honourable hero in the form of Aramis - a 'daredevil' who is highly religious and raised to be a priest. Santiago thinks Aramis gets into the most trouble but agrees that the whole gang has a penchant for peril. 'It was a time in France where they knew it was a lifestyle that was about to end, so they are living life to the full', he says, but replicating that on set brought up many challenges; most memorably, the heat: 'We have had some days of 35 or 36 degrees fighting in the leather costumes - running up and down and doing these pretty elaborate 45-second to one-and-a-half-minute fights, which require really intense bursts of energy.'
