This is a film by Aneil Karia director of the Long Goodbye which was the Oscar winner for Best Live Action Short Film. Surge is about a man on the verge of a breakdown played by Ben Wishaw and you have the frenetic energy throughout the whole film as his character goes into a spiral downwards. 

The whole thing was shot handheld and in a frenetic way to encompass what Ben was doing in his performance. Scenes were done in one takes and spanned various locations so it was shot fast and logistically challenging. I had various mixing recorders to grab the dialogue that I moved between during scenes if they spanned large areas. Often I just needed to be fast on my feet and move quickly between sets. Various boom operators were used to be able to cover areas where it was dialogue heavy. It was a challenging yet really rewarding!
