TextBlock Glow Effect Inside Button - wpf

Question

I have a button with it's control template set to a TextBlock. I want the text to "Glow" when the mouse is over it or it has gained focus by moving to it via the keyboard. I can't seem to get this working as I presume I'm setting the effect in the wrong place. Has anyone done this before that could share the xaml for it. Here is my style so far.
<!--Back Button-->
<Style x:Key="MoviesBackButton"
TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<TextBlock Text="Back" Style="{DynamicResource MoviesButtonBackTextBlock}" />
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Width"
Value="40" />
<Setter Property="Height"
Value="25" />
<Setter Property="VerticalAlignment"
Value="Top" />
<Setter Property="HorizontalAlignment"
Value="Left" />
<Setter Property="Margin"
Value="10,5,0,0" />
</Style>
<Style x:Key="MoviesButtonBackTextBlock"
TargetType="TextBlock">
<Setter Property="Foreground"
Value="{DynamicResource MoviesButtonBackTextBlockForeground}" />
<Setter Property="FontFamily"
Value="Segoe UI Light, Lucida Sans Unicode, Verdana" />
<Setter Property="FontSize"
Value="20" />
<Setter Property="TextOptions.TextHintingMode"
Value="Animated" />
</Style>
<LinearGradientBrush x:Key="MoviesButtonBackTextBlockForeground"
EndPoint="0.5,1"
StartPoint="0.5,0">
<GradientStop Color="LightGray"
Offset="0" />
<GradientStop Color="Gray"
Offset="1" />
</LinearGradientBrush>

Here's one solution for mouse-over glow. You can add similar event triggers for Button.GotKeyboardFocus/LostKeyboardFocus.
If I was doing this for real, I would probably create a custom control and use visual states. Search for 'Visual State Manager' for more information.
<Grid>
<Grid.Resources>
<Style x:Key="TextBoxGlow" TargetType="{x:Type Button}">
<Style.Triggers>
<EventTrigger RoutedEvent="Button.MouseEnter">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(Button.Content).(TextBlock.Effect).Opacity" From="0"
To="1" Duration="0:0:0.5" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
<EventTrigger RoutedEvent="Button.MouseLeave">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(Button.Content).(TextBlock.Effect).Opacity" From="1"
To="0" Duration="0:0:0.5" />
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
</Style.Triggers>
</Style>
</Grid.Resources>
<StackPanel>
<Button Style="{StaticResource TextBoxGlow}" Margin="5">
<TextBlock Text="I'm glowing" FontSize="28" Padding="10">
<TextBlock.Effect>
<DropShadowEffect BlurRadius="8" Color="Crimson" ShadowDepth="0" Opacity="0" />
</TextBlock.Effect>
</TextBlock>
</Button>
</StackPanel>
</Grid>
