Costumes for our actors for our opening sequence:

This type of dress code will be applied to Kirrill (Head of the Terrorists), to show that he can be associated with wealth because he is smartly dressed. And that he doesnt do any of the dirty work.

For the other two terrorists they will be dressed in army kit, to show that they have to do all the dirty work, and dont have the same wealth as Kirrill.

This type of clothing will be applied to Simon the spy to show that he dresses up casually to blend in with other citizens, not to let anyone find out his true identity.
