Why they shine
Sean Penn has collected three Oscars across two categories and has never appeared to enjoy any of them. The third came on 15 March 2026, at 65, for Best Supporting Actor as Colonel Steven Lockjaw, the volatile, self-maddened officer in Paul Thomas Anderson's One Battle After Another. Lockjaw is a white nationalist commander whose fixation on a Black revolutionary exposes the rot inside his own certainty, a part Penn built on his characteristic stillness before violence. He did not attend the ceremony; Kieran Culkin, the previous year's supporting winner, accepted for him with the line that Penn could not be there, or did not want to be.
