Jesse Armstrong talks about the pressure of following the success of "Succession" with his new movie "Mountainhead."

Just like Succession, HBO's gone-but-not-forgotten drama series, Mountainhead comes from the satiric mind of Jesse Armstrong and focuses on a group of unserious billionaires. However, critics aren't as enthusiastic about the new TV movie as they were with its Emmy-winning predecessor.

Armstrong is still fascinated by the egotistical rich kids who hold our fates in their hands, but his latest project lacks the lightning-in-a-bottle chemistry that made "Succession" such a triumph.
