How to get Spinner OnListItemSelected to work

I am currently trying to implement a Spinner within my android application. I am having trouble with getting the OnItemSelected method, to open a new class based on what item was selected.

I have the code shown bellow, which does not seem to work, Also since adding this is, it now from the menu when I click the button to open Film and TV it opens the wrong layout, but nothing changed other than adding the bellow code.

What should happen: Activity Starts --> Click on Film and TV --> Select item from Spinner --> New class opens based on what Item was selected.

What Happens now: Activity Starts --> Click on Film and TV --> Wrong layout opens --> Press back on phone --> Right layout opens --> Select item from Spinner --> Nothing Happens

Code: 

String classes[] = {"SeanConnery", "BillyConnoly", "JamesMcAvoy", "KarenGillan", "KellyMacdonald", "AshleyJensen"};
    @Override
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

    String classSpot = classes[pos];
    try{
    Class nextClass = Class.forName("com.example.famouspeople." + classSpot);
    Intent ourIntent = new Intent(Film.this, nextClass);
    startActivity(ourIntent);
    }
    catch(ClassNotFoundException e){
        e.printStackTrace();
    }
    }

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.famouspeople"
android:versionCode="1"
android:versionName="1.0" >

<application

        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity

    </activity>
            <activity
        android:name="com.example.famouspeople.JamesMcAvoy"
        android:label="@string/app_name" >
    </activity>
            <activity
        android:name="com.example.famouspeople.KarenGillan"

change your mainfest from 

<activity
        android:name="com.example.famouspeople.SeanConnery"
        android:label="@string/app_name" >
    </activity>

To

<activity
        android:name=".YourJavaClassName"
        android:label="@string/app_name" >
        <intent-filter>
             <action android:name="com.example.famouspeople.SeanConnery" />
             <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
</activity>

to create intent you can do something like this...

final Context context = this;
Intent intent = new Intent(context,youractivity.class);
            startActivity(intent);
