Let's bind one more view. Bind an ImageView member variable. Name it mMovieImage and again use the ID from the layout file for the ImageView.

Bummer: There is a compiler error. Please click on preview to view your syntax errors!

You're using InjectView. Inject was changed to Bind so you're supposed to use BindView. This is how your code should look like (not much difference just replace InjectView with BindView): 

import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

public class MovieActivity extends Activity {
    @BindView(R.id.movieTitle) TextView mTitleLabel;
    @BindView(R.id.movieImage) ImageView mMovieImage;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
        ButterKnife.bind(this);


        // The rest of the code is omitted for brevity :)
    }
}
