Prayer in our trailer - dialogue

In the beginning of our trailer, our main actress is reciting a prayer. Why we thought our main actress should be reciting a prayer right in the beginning of the trailer because it would make the audience wonder what is going on and get them questioning as she sounds as if she is praying with a fear and not praying in peace.

Hail Mary, full of grace.

Our Lord is with thee.

Blessed art thou among women,

and blessed is the fruit of thy womb,

Jesus.

Holy Mary, Mother of God,

pray for us sinners,

now and at the hour of our death.

Amen.
