JASON SCHWARTZMAN WAS only 18 when his career began. His very first movie was 1998's Rushmore, the second film from writer/director Wes Ande rson, and it finds Schwartzman in the lead role of the too-smart-for-his-own-good high schooler and self-styled playwright Max Fischer.

Jesse Armstrong traded Succession ‘s Roy family for a tech titan getaway in his new HBO film Mountainhead, which follows the events of a pivotal poker game set at the titular estate.

With his combination of delusion and wholehearted sincerity, Souper is a bit like Mountainhead 's answer to Connor Roy. Ahead of the film's premiere, Schwartzman told TV Guide about Mountainhead 's condensed shooting schedule, the particularities of working with Armstrong, and how he sees Souper's place among the group.
