Nominees in the category included Jonathan Bailey, Yura Borisov, Kieran Culkin, Edward Norton and Jeremy Strong

Kieran Culkin won the award for best actor in a supporting role Sunday night at the 2025 SAG Awards. Pamela Anderson presented Culkin with the statue, which he noted was an "incredibly heavy award" before poking fun at the length of Adrien Brody's acceptance speeches.

Culkin was accepting his award for Outstanding Performance by a Male Actor in a Supporting Role, which he won for 2024’s “A Real Pain.”
