The Big Short-- the Movie and the Book
I haven't seen the movie. (I might, without Tonia, who'd be bored to tears. We'll see.)
But I have read the book and reviewed it here.
I've also read John Allison's helpful book on the "Financial Crisis" and reviewed it here.
For other resources on the movie, check out John Goodman, Peter Wallison, and Robert Murphy. This review by Doug French is the strongest on comparing the movie and the book.
