Popatopolis is an intriguing 2009 documentary film that chronicles the life and unique career of the legendary B-movie king, Jim Wynorski. Known for his prolific output in the realm of low-budget exploitation cinema, Wynorski holds a special place in the pantheon of cult film directors. This lively and engaging film takes audiences behind the scenes of the B-movie industry, while also examining the life, professional struggles, and creative processes of Wynorski.

The film starts with an introduction to Jim Wynorski, a man who has been in the entertainment industry for over three decades and released over 150 films during that time. He is most known for his often tongue-in-cheek, low-budget exploitation films that span a range of genres, from horror and sci-fi to sex comedies. Popatopolis chronicles the making of one such film, 'The Witches of Breastwick' - a ripe example of Wynorski's trademark style - providing a fascinating and intimate look into the world of B-movie production.

The major selling point of Popatopolis undoubtedly lies in its insightful exploration into the ever-enticing world of exploitative filmmaking. The viewers soon find themselves submerged and invested in the chaotic yet creative process of bringing a B-grade movie into existence. Wynorski, shown as uncompromisingly passionate about his work, leads his rag-tag crew with the determination to finish the movie in just three days.

Throughout Popatopolis, the spotlight is shared between Wynorski and the two main leads of 'The Witches of Breastwick', Julie K. Smith and Julie Strain. These actresses provide additional perspective, fleshing out a fuller image of the working dynamic on such low-budget sets. They, along with the rest of the crew, discuss the high-pressure, limited-resource environment of quick production, and the unique thrill that comes with it.

The documentary is aptly punctuated with concise and engaging interviews with Wynorski’s colleagues, friends, and stars. It provides a more in-depth understanding of the man behind the camera, delving into his career, techniques, ethic, and impact on the film industry. The interviews discuss his unwavering passion for cinema, his eccentricities, and his exceptional skill at creating popular, profit-turning films on a shoestring budget. His colleagues, who have spent years with him in the business, share incredible anecdotes about his work ethic and describe him as a ‘mad genius’.

A stellar segment of the film encapsulates the ‘golden era’ of B-movies, roughly spanning the 1980s and 1990s, revealing Wynorski’s significant contributions to it. He became a connoisseur of low-budget filmmaking during this period, producing an astounding number of films that loyally followed the B-movie formula: minimal costs and maximum returns.

Between the behind-the-scenes footage, interviews, and production anxieties, director Clay Westervelt weaves a sympathetic portrait of Wynorski. Westervelt does not flinch from showing the director's temper tantrums or the crew's exasperation. Yet, he also captures Wynorski's charisma and dedication, qualities that explain why so many talented people choose to collaborate with him despite the demanding working conditions and tight schedules.

Popatopolis explores the drive necessary to create in an industry where artistic vision often clashes with economic necessity. In Wynorski's world, time is measured in shots completed, not hours passed. Every sunrise means a missed deadline, and every shot is a step closer to completing the film.

Through the lens of Jim Wynorski and his determination to produce 'The Witches of Breastwick' within three days, Popatopolis speaks a universal truth about filmmaking: it is a labor of love, only to be undertaken by those with absolute passion for the art. At the heart of the film, there is an inspirational message for all artists dealing with limited funds and maddening time restraints - work with what you have and make it the best you can.

It's a documentary that will be well received by not only fans of Wynorski but also fans of cult cinema in general. Despite its niche subject matter, Popatopolis offers universal themes that will resonate with a broad audience. For aspiring filmmakers, it’s a deep insight into the pressures and pleasures of the creative process under constraints. And for film enthusiasts, it delves into a fascinating, often overlooked corner of cinematic history.
