The documentary "Blood, Sweat and Fears" on BBC 1 uses a mixed format of interviews, voiceover, archive footage, and actual footage to explore phobias in a non-linear narrative. It follows a single topic without branching off. The documentary employs techniques like the rule of thirds for interviews, clear text for names and relevance, relevant background images, cutaways during interviews, and simple cuts between sections. A radio trailer promotes the documentary using clips, the same voiceover, scheduling details, and music from the show.
