Jason William Day

Jason William Day, often known simply as Jason Day and nicknamed "DoomsDay," is a Canadian multifaceted talent whose career spans professional Mixed Martial Arts (MMA), acting, and stunt performance. Born on March 18, 1979, in Lethbridge, Alberta, he began his professional MMA career in 2002. He amassed a professional record of 19 wins and 12 losses, becoming a known force on the Canadian regional circuit before earning a spot in the Ultimate Fighting Championship (UFC). His UFC debut was a memorable upset win over veteran Alan Belcher at UFC 83. After a career-ending traffic accident in 2011, Day successfully transitioned his real-world combat skills into the film industry as an actor, stunt performer, and fight choreographer. His film credits include a role in the action-thriller Skyscraper opposite Dwayne "The Rock" Johnson, the horror-thriller Longlegs as "Father Camera," and the action-comedy film Playdate (2025), where he squared up against star Alan Ritchson as the character "Clive." He is also working as a fight choreographer on upcoming projects like the movie Ballastic.
