How much slow-motion can one episode have?
In the case of the 10K-featured episode...lots! I think they had about 20 minutes worth of script before shooting and then just relied on slo-mo to fill out the rest of the action. Still, it worked for Garth Marenghi with his real-time slow-motion running..
Best films ever:
