IMDb Connector don't import some movies informations!

First thank you for this plugin, it works perfectly, except that sometimes it does not import information some movies, I don’t know why! The title is exatement like IMDB, I even tried with ID movies but it still does not work,

I Use this function:

function like_content($content) {
if (is_single()) {
                $original = $content;
		$t=get_the_title();
		$y=get_imdb_movie_detail($t, "year" );
                $content = "<div>Year : <a href='https://romance7movies.com/tag/".$y."/'><b>";
		$content .= $y;
		$content .= "</a></b></div>";
                $content = $original.$content;
}
return $content;
}
add_filter('the_content','like_content', 0);

This is the final result normaly : Romance Movies

But somtimes, it dosen’t import informations.

Some idea plz?
