If you're writing 30 minutes sitcom or comedy drama scripts, you'll want to get the structure right. But there is definitely a lack of really clear advice out there about structuring your episode. Here's an hour-long video in which Chris Head uses clips and script excerpts to look at the three act structure often seen in TV comedy.
Chris says: "As a writing coach and mentor, I read a lot of thirty-minute TV comedy scripts. One thing that is often lacking is structure. Now, you can of course have a script that is perfectly structured but still falls short in terms of characterisation, story, situation... funniness. However, you can also have a script that has huge potential in all these areas but is let down by poor structure.
"Luckily, it's quite simple to get your head round the structure of a thirty minute script, and once you get into it you find it really helps with the storytelling. Indeed it can also help with making sure your episode is funny and character driven. In this seminar I take you through the three act structure of your script, following the tuning point, midpoint, crunch point (or 'worst point') structure and how to manage multiple storylines."
