A menacing-looking jungle spider the size of a hand is filmed crawling across the face of a Royal Marine in an advert that was sure to leave arachnophobes panting for breath.

The 'Spider' film from the archives of military recruitment advertising explored what might make even a trained combat specialist break cover but suggested that Royal Marines' training meant that they would maintain their focus no matter what terrors they faced.

The Marine in question was filmed ignoring the huge arachnid crawling up to his face and staying poised and focussed on the mission.

The filmmakers wanted to keep the advert as authentic as possible so used real combat-ready Royal Marines Commandos on deployment.
