The podcast episodes provided discuss the importance of practical effects in filmmaking, particularly in the context of low-budget and independent productions.

The episodes highlight the use of practical techniques such as stop-motion animation, creature designs, and other physical effects to bring the surreal and imaginative elements of films like "The Dungeonmaster" and "In a Violent Nature" to life on screen.

The discussion of practical effects is further expanded upon in the "Special Effects: A Short History" episode, which provides a comprehensive overview of the history and evolution of special effects in movies, from their origins in the late 19th century to the present day.
