Beloved stars like Catherine O'Hara, Chadwick Boseman and Heath Ledger may be gone, but they'll never be forgotten. These three actors and many more have won awards posthumously following their deaths, keeping their legacies alive. Boseman won a Critics Choice Award and a Golden Globe Award the year after his death in 2020. Ledger won his only Academy Award in 2009 after dying one year prior from an accidental overdose. O'Hara, meanwhile, earned a SAG's Actor Award in 2026, just one month after her death in late January.
