Threatened

When the only witness to a murder is threatened, Detective Anna Davis is in charge of keeping him safe. This sounds easier than it is. The witness has an unavoidably busy life as an actor. Not just any actor, Lee Pace.
He never follows Anna's directions on safety, instead he assumes that Anna will always be there. Anna becomes concerned when the star starts taking unnecessary risks, and confronts him.

"Why do you insist on making yourself a target?!" I scream.
"Because that's the only way you'll see me."
