Clark DeBussyCharacter guide · Hamish Linklater

Hamish Linklater portrays Clark DeBussy in Legion. FX’s official cast introduction frames David Haller as an opponent unlike those Clark has encountered before. Start with the first season to see that confrontation develop rather than using later-season descriptions that disclose its consequences.

Notice what he treats as a threat

Watch how Clark responds when information does not fit the situation he expects. The questions he asks and the decisions he makes offer a different perspective on David from the one the viewer experiences inside David’s story.

Begin with Legion season one and follow seasons two and three in episode order. The original catalog records below remain intact; this introduction does not summarize Clark’s later decisions or the outcome of the conflict.
