Efficient use of actors, settings, props, sounds

Within our thriller we used Kayleigh Neil, Kayleigh Neil's little brother Connor Neil who is 13 and myself. To start of with we was planning to use a young toddler, or a baby, but we fought it easier to use Connor as we would have more control and would get it done quicker as we had little time. we filmed our thriller in Taylor's house as it fitted in well as the main story is about baby sitting. Some of the sound we used we created ourself such as the doors closing, dropping cans to create a bang! however the music we have in the background we got it of a music site 'news ground'.
