 Before the principal photography began, Jennylyn Mercado (qv) was  invited by her boyfriend Patrick Garcia (I) (qv) to watch an  archery tournament in Batangas. She attended not only to support  Patrick but also to observe and do research for her role in this  movie where she plays an archery athlete. She was later trained by  members of the athletic archery association for her role. Members of  the group were in the set for assistance.
