Most of Corman’s films shot in 10–15 days. The Little Shop of Horrors shot in two days and one night. This isn't about speed; it's about eliminating waste. Every extra day adds catering, equipment, and crew costs that destroy profit margins.
To understand the book, you must understand the author. Roger Corman (1926–2024) was often called the "King of the B-Movies." He directed and produced hundreds of films, ranging from horror and sci-fi to biker dramas. Most of Corman’s films shot in 10–15 days
While Hollywood studios were spending millions, Corman was making films for pennies—and making a profit every single time. He is also famous for giving starts to now-legendary directors like Francis Ford Coppola, Martin Scorsese, James Cameron, and Ron Howard, and actors like Jack Nicholson and Robert De Niro. Every extra day adds catering, equipment, and crew
“How I Made a Hundred Movies” relies on velocity. Corman famously shot The Little Shop of Horrors in two days and one night. Why? Costs are linear. Every day you rent a camera, you burn cash. While Hollywood studios were spending millions, Corman was
Corman waited for a hit genre (beach parties, biker gangs, teenage car crashes) and then flooded the market with 5–10 variants before the trend died. He never tried to guess the next big thing; he exploited the current big thing until it bled.
Corman never tried to beat Disney at the box office. He sold to the drive-ins and the grindhouses. The modern equivalent? Don't try for a theatrical wide release. Sell directly to a niche streaming service, YouTube, or a specific subreddit community. He targeted places where the projectionist was the popcorn seller. You target low-overhead, high-volume platforms.
