Onscreen performer Michael Kelly specialized in slightly rough-hewn, working-class character roles. Kelly premiered on the big screen with occasional bit parts in the late '90s, but achieved much greater prominence by playing a security guard in the 2004 supernatural horror remake Dawn of the Dead, and by essaying one of the supporting roles in the Ericson Core-directed inspirational sports drama Invincible (2006), starring Mark Wahlberg and Greg Kinnear.
Kelly also acted regularly on the small screen, with numerous guest roles as well as a longer stint on The Sopranos as FBI agent Ron Goddard. In 2007, Kelly signed to appear in Tooth & Nail, a post-apocalyptic thriller about a courageous band of holocaust survivors who hole up in a hospital and try valiantly to defend themselves from invading cannibals. ~ Nathan Southern, All Movie Guide.
