Tech specs: Sony F55, Angenieux Optimos 15-40mm, 28-76mm / Zeiss CP.2 135mm / 24fps / 1.185:1 / 2K
That looks like an aspect ratio. If it's for cinema release, why not 1.6:1 ?
However I really look forward to this. Louis Theroux does very natural interviews that make you as the viewer feel part of the action.
