I remember watching a movie where a demon is trapped in an electric cage and being studied. At some point, it breaks out and goes on a rampage to escape the underground research facility. And I also remember around the last scene, a woman (who in a way helped the demon escape) is bouncing a basketball in an elevator with the woman, and the elevator goes out of the facility. The demon by the way is completely invisible. I think the poster was also mainly blue with a ring and a black silhouette in the middle or something like that.
