This book is the absolute bible for Improv. Whether you're taking your very first Improv class, or are a seasoned performer, you will find that referring back to this book is absolutely a must. Charna and Del (RIP) are gold standard directors in the industry, as such the information that is imparted is something you will use through your Improv career.The funny anecdotal information along with the full discussion of "The Harold" form of Improv is much appreciated. The book does not become stagnant at any point. This is why it remains as the gold standard.The director for our troupe also offers classes for beginning Improv students. This is the first text book that is requisite, there is also "recommended" reading, but "Truth in Comedy" is a requirement, and for a good reason.Review Additional informationFriends and new friends, if this review has been helpful, please click YES.

I rely on reviews, videos and, photos when making my decision to buy a product online, and I would like to know if my reviews HELPFUL to you…. I would also like to know if I need to add anything. I take pride in offering descriptive reviews and honest feedback.ABOUT ME: I have been an Amazon Prime customer for quite a while and I really enjoy writing reviews – I love shopping actually, and love sharing my finds.My personal criteria for products:• 1 star (I do not like this item or product). I feel it's a waste of money. Would never use it again. Would not recommend. Either throw away or return it.• 2 star (Not a big fan): Would not purchase again nor share it with my friends, but may still have at least 1 positive thing about it.• 3 star (It’s Fair): Product has both positives and negatives, and I may or may not continue using it. It might be a better item for another person. If I think of who may like it better I will likely write about who I think it would work for.• 4 star (Pretty, pretty, pretty good – to quote Larry David): Item is accurately described. May have 1 or 2 things I might potentially change, but not a deal breaker. Would recommend it to friends and family.• 5 star (It is perfect and I LOVE it!) Practically perfect. Amazing quality and a must have. It means I’m “Over the Moon” with it and would not only recommend, but would purchase for others and continue to purchase for myself.
