Display Year in WP Title

Good day,

I create a new movie theme. I added some custom field in my “New Post”.
Screenshot: https://s32.postimg.org/i5a960u39/image.jpg

I’m using this fuction code:

function movie_content(){
	global $post;
	$details = get_post_meta( $post->ID, '_movie_site', true );
	$has_data = true;
	if( !is_array( $details ) ) $has_data = false;
add_meta_box( 'name', __( 'Movie details', '123' ), 'movie_content', ABC_MOVIE, 'normal', 'high', null );

In Admin dashboard, when i create a “New Post”, I’m using this below code for display “Year” form (view screenshot).

<tr>
	<th><label for="movie-site-year"><?php _e( 'Year', '' ); ?></label></th>
	<td>
		<input name="movie_site[year]" type="text" class="fullwidth" id="movie-site-year" value="<?php echo $has_data?$details['year']:''; ?>">
		<small class="desc"><?php _e( 'Movie release year', '' ); ?></small>
	</td>
</tr>

And I using this code for display “Year” in my wordpress template (example: 1997).
<?php echo $movie_site['year']; ?>

Everything work fine, I can display movie Year in my single.php template.

***

My question is, I want that “Year” appear beside my title. But i don’t know how create it.

My current Post title: Titanic.
I want something like this: Titanic (1997).

Can someone help me, please!

Thanks
