interface, class, or enum expected

Is this code challenge broken or is there something that I am missing?

''' ./MovieActivity.java:6: error: class, interface, or enum expected @InjectView(R.id.movieTitle) TextView mTitleLabel; ^ 1 error '''

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

@InjectView(R.id.movieTitle) TextView mTitleLabel;

public class MovieActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
      ButterKnife.inject(this);

        // The rest of the code is omitted for brevity :)
    }
}
activity_movie.xml 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/movieTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="32sp"
        android:text=""
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

    <ImageView
        android:id="@+id/movieImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@id/movieTitle" />

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/movieTitle"
        android:layout_centerHorizontal="true"
        android:id="@+id/linearLayout">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView"
            android:layout_weight="1"
            android:gravity="left" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView2"
            android:layout_weight="1"
            android:gravity="right" />

    </LinearLayout>

</RelativeLayout>

Jeremiah;

You need to put the @InjectView statement inside your class definition.
