Just wanted to mention to the forum that there is a fantastic HBO miniseries on the Chernobyl disaster that just recently was aired. For those that have HBO subscriptions, I highly recommend the series. It is separated into five episodes and it goes into great detail on the causes of the disaster, the people involved in trying to contain the fallout and a lot of the political machinations that were occurring in the Soviet Union at the time.
Very well acted with fantastic cinematography and visuals. HBO can be kind of hit and miss with its programming but I have to admit, they knocked it out of the park with this one.
