Thriller characters

the two characters we plan to have for our thriller are 2 mysterious loners one will be chasing the other as he as the antagonist and the protagonist will be desperately trying to get away from the other we have not given them names as we don't want to reveal much about the narrative in the opening scene but I wil play one of them and Ryan Martin will play the other one will be wearing a white shirt and the other a black to give the characters contrast and to differentiate between god and evil
