Getting strange characters in fields with output from json c++

I'm using the json value I receive from my .get(movie) function to get the values of each of the keys within my json movie object. I'm trying to output it into fields in a fltk GUI, which need to be const char * type. However, I'm getting strange characters instead of my values. Is there an obvious issue here?

 Json::Value result = m.get(movie);
 std::cout << result << endl;
 const char *released = result.get("Released", "NULL").asCString();
 releasedInput->value(released);
 const char *rated = result.get("Rated", "NULL").asCString();
 ratedInput->value(rated);
 Json::Value actors = result.operator[]("Actors");
 const char *plot = result.get("Plot", "NULL").asCString();
 plotMLIn->value(plot);
 const char *runtime = result.get("Runtime", "NULL").asCString();
 runtimeInput->value(runtime);
 Json::Value genre = result.operator[]("Genre");
 const char *filename = result.get("Filename", "NULL").asCString();
 filenameInput->value(filename);
 const char *title = result.get("Title", "NULL").asCString();
 titleInput->value(title)

I've pasted only the relevant lines within my function. If more clarification is needed, I'm happy to provide it.
