As a reviewer noted, "Pilgrim's Progress: Journey to Heaven is a faithful and creative adaptation of a timeless classic. The genius lies in bringing Christian and his fellow travelers into a modern context.
I haven't seen the movie, but the trailers I have seen are gripping, and yet seem to accurately portray the message of the book.
Check them out for yourself:
(watch the trailer on the main page)
(slight differences from the main trailer)
(much different from the first two trailers)
It's impossible to film the whole book in 1 hour and 43 minutes, so hopefully the film will motivate people to read the book. If you don't own a copy (shame, shame!) you can read it online here.
