Scott Foley and Guillermo Diaz on why Scandal actors make such good serial killers

In a weird coincidence, Scandal co-stars Guillermo Diaz and Scott Foley were both cast as serial killers in Investigation Discovery true crime movies. Diaz played Rodney Alcala in the Dating Game Killer, the story of a murderer and rapist whose superficial charms landed him an appearance on The Dating Game during his spree. Meanwhile, Foley played Jeffrey MacDonald, better known as the Green Beret Killer, in Final Vision. In the video above, the pair discusses what led them to take on these roles and how their experience on Scandal helped them prepare.
