On the shoot day, I was in charge of the props, location, how the scene would look like. I also created and developed the plot for our opening sequence, along with Matt, who helped us out through the the filming day.
Me and Liza went to the Theater department, to get the props, we needed for our opening sequence. We managed to find Artificial blood, make up, fake guns, crime investigation tape, leather jackets and spoon, to spill blood on the walls.  
Not to mention, than I also collected disinfection gloves from the Art department. So, everyone took it very professionally and were prepared in advance. 
In my opinion, I particularly did well in acting, although, I've never done it before.
I had to play a very cheeky crime inspector, who was apparently very good at doing his job. As I reference, we used a scene from Hard Boiled, starring John Woo as an inspector.
