This document outlines a formal proposal for a documentary titled "Lighten Up" about smoking. The documentary will use a mix of interviews, narration, and archive footage. It will air on Channel Four and target those aged 16 and older. The narrative will be single-stranded and linear, beginning with the history of smoking and ending in an open-ended manner. Primary research will include interviews and cutaway footage, while secondary sources comprise archive clips, music, and online resources.
