The soundtrack with the recognizable sound from his prepared piano play and the use of alien objects on top of the hammers and strings.

The impact of the scenes are furthermore supported by the use of strings and drums.

Harington stars as Catesby, who was a committed Catholic at a time when Protestant England persecuted Catholics relentlessly.
