Fan CastingIron Man 3: Retribution

Description of Obadiah Stane (Flashback):

[Mandarin] - Some of my men collaborated with that man that day. Even if you had reached me, they would die, because I would remember this disgusting fact. [Tony] - My father and I really shouldn't have trusted Stane so much that we didn't see what he did. - Would you say the same if I hadn't blown up your mansion? - I should have been more careful before, and I realized that. - Great...as they are both already underground, the only thing left is for you to pay. The film places a heavy emphasis on Stark Industries' old missile projects, and how both Tony and his father relied on Stane to manage most of the process, without knowing what was actually going on.
