Blast (1997)

Terrorists attempt to disrupt the Atlanta Olympics by kidnapping the U.S. women's swim team. If their demands are not met, the team will be executed. Only janitor Jack Bryant (Linden Ashby), a former Olympic gymnast champion of Tae Kwon Do felled by injuries and alcoholism knows of their real plans. And only he, with the guidance of former terrorist-fighter Leo (Rutger Hauer), can stop them.
