I can only recall one scene from the movie (it may have been a TV movie but I don’t believe so). The protagonist (a male action-y type) was visiting the home of an older man who either currently was or used to be a Nazi hunter, seeking information about something or other. At some other point (maybe right afterwards, maybe not) the older character is shown to be murdered, perhaps as a result of his interaction with the main character. I believe these scenes take place somewhere in Europe. I don’t recall specifically but I think the movie is from the first decade of the 21st century.

Note: My memory for this movie was triggered by that related subplot from American Horror Story season 2, but that’s not what I’m thinking of.

*** The older actor who played the Nazi hunter in my mind strongly resembles Jerry Orbach. If I could remember the name of this actor, I could find the movie, but of course I don’t, and google searches for “actor who looks like Jerry Orbach” have proved fruitless.**
