Like @AhnyerKeester, I saw Orca when it was initially released. It was as a Dino De Laurentiis-ful double-feature with King Kong at our local drive-in. I was a kid, so I actually enjoyed it.
And, it does have a soundtrack by the legendary Ennio Morricone so it would fit in The Curious Case of Awful Movies with Great Soundtracks thread.
