Well, this should be interesting. I can't think of a more appropriate period of time other than now to release this kind of movie. I understand that Part 1 covers roughly one-third of the book. It's relatively low-budget with an undistinguished cast but I've read some fairly positive reviews about it thus far. The trailer below has over 1.3 million hits so there is definitely widespread interest out there.
In all honesty, I would recommend reading the book first. My hardcopy has 1,168 pages, but I can't pinpoint a book of this size that I've read faster. Ayn Rand envelopes the reader. It's a gripping tale. And the relevance is creepy considering that this book's copyright date is 1957. Who knows? Will the lights be on in New York by the time Part 3 is released?
