Psssst! Wanna know the meaning of life and the secret to human nature?
Then read this book, Improvisation and The Theatre. (Just read a few reviews and they'll confirm what I'm saying).
It not just about Impro and the theatre. It's about life, order, learning, what's attractive in people, how we play out in life. It's the worst book cover I've ever seen, but it's a great book.
The book is a great pointer to why some people are compelling on camera, and in real life for that matter. It's all a game.
And if you want to burn an evening up, go search "Whose Line is it Anyway" on YouTube!
