While clearly not all of Hollywood portrays the industry accurately, from my perspective the movie was incredibly reflective of the players in the space, and the dynamics.

I worked in the mortgage/CDO/CDS industry for 10yrs during that period (2005-2015).

If anything, the movie was too positive. There aren't as many players like Steve Carell's character who are worried about the world, they are usually worried about how to liquidate their book at the right time.

The bit about getting marked the wrong way was especially spot on.

Another very accurate movie: "Margin Call"
