Jack O'Connell turned heads at the 98th Academy Awards by putting a devilishly stylish spin on classic black-tie dressing. The Sinners star, 35, showed off his dark side while flashing a grin and exposing his prosthetic, blood-soaked fangs on the red carpet at the Dolby Theatre in Hollywood on Sunday, March 15. O'Connell, who portrays the ancient vampire Remmick in the horror drama, arrived at the 2026 Oscars in a sharply tailored tuxedo.
