Jesse Armstrong hadn’t planned on making another project about billionaires. It inspired him to write and direct his first feature: Mountainhead, a movie about three tech billionaires and their less rich, deeply insecure friend, all of whom have far too much power at their disposal. “I couldn't get the … tech voice, tech man voice, a billionaire, out of my head,” Armstrong says, noting that to him, that voice embodies both “supreme confidence in their analytical abilities” and “arrogance.” Armstrong is being nice here. While Carell says there were upsides to the tight turnaround—“everyone's just trusting their gut”—Schwartzman says quickly attaining fluency in the “tech voice” Armstrong was going for was a challenge for him. “At a certain point I said to Jesse, if you ever want us to say anything extra, do you have a glossary or a dictionary,” Schwartzman says.
