Hmm...Haven't seen 'Passion of The Christ', but on a similar note, I have seen 'Jesus Christ Superstar'. In fact, I just finished another viewing of it (those songs are REALLY catchy).
Now, to connect this to The Lion King (in an attempt to make it semi on topic): The lyrics for the songs in Jesus Christ Superstar were written by Tim Rice of TLK fame. He also wrote the play adaptation of it. And the director of the movie adaptation went to my high school.
...Maybe I should stop before I start rambling on.
Anyway, on the said aniversary date, I'll have to have a tribute viewing of TLK.
