C.S. Lewis wrote that Jesus was either a liar, a lunatic, or the Lord He claimed to be. Unfortunately, on stage and film many actors slip into the "lunatic" portrayal--especially during difficult (usually angry) scenes like the cleansing of the temple and confrontations with the Pharisees. And those who avoid that pitfall often portray Jesus as a mystic with His head in the clouds, completely out of touch with reality.
But through great prayer and study Bruce Marchiano captured a portrayal that not only overcomes these two problems but does so much more. Often his portrayal is surprising and even amazing, but for students of the New Testament, it rings true. This is a Jesus who is passionate and full of joy.
I have read this book over and over and never cease to be inspired by the remarkable insights it provides. For scholarship, try Philip Yancey's "The Jesus I Never Knew." But for the remarkable revelations only an actor discovers, read this amazing book.
2018--update.
I just read this again. It's still a great book. Over the years, it has often served me as a sort of Advent Calendar, and I have read it in anticipation of playing the role of Jesus on stage. This season was no different--the book again enriched not only my experience and my acting, but gave me specific things to pray about both off-stage and on. I borrowed Bruce's prayer: "Make me a puppet on your strings," and a second for the audience: "Melt the stone-cold hearts."
This year I also found myself applying a specific idea based on Marchiano's repeated emphasis on the joy and laughter of Jesus. I found a way to work an actual belly laugh into the show. Some would find that sacrilegious or not-serious enough for a portrayal of Jesus--and those are just the ones who might need to see that God's Son (and God the Father) not only laugh, but INVENTED laughter.
Anyway, I do love this book.
