When writing a sketch, do you think it's better to write as much as possible, film it and then see what works and what doesn't. Or would editing the script tightly before filming be better?
I'm talking at an amateur level here, because I can imagine by the time you're Pro, there will be script editors cutting your work to pieces for you and you'll probably have the experience to know what works and what doesn't anyway.
I've never filmed a sketch before, is it really a lot of hard work, is it best to keep it as simple as possible?
