Sinister Pictures' opening title sequence was filmed many times and not always even about the same idea; we started with the idea of Pandora's Box in the first place but changed it to Room 101 over time.
The idea behind our final opening title sequence (OTS) was that the character is going insane so we need to show different levels of progress and also show a large variety of movement in a small space. When filming we had to try many different angles and distances between actor and camera, to ensure that all shots would show what they are intended to. Some of these we explored beforehand to make sure our initial ideas are included.
Some shots that we decided to include needed to be a high angle on the victim so when trying that out, we realised that it works really well just needs specifying and playing around with other clips to make sense when in order with other shots.
