These are the worst movies Arnold has made in my perspective.
This movie, which I believe was his first, has Arnold playing Hercules. This is an intentionally stupid movie, but really bad even though it's supposed to be dumb. They even have a voice over actor in place of Arnold's real voice.
The first Conan movie was pretty bad even for it's time, but the people liked it. This is the second movie, it's so bad it makes the first one look good.
Arnold getting pregnant, what could be funnier than that? Anything else. Even if you can accept the story line of Arnold's character becoming pregnant, this movie is still terrible.
This movie is just so bad in general, it has made many worst movies lists. Arnold plays Mr. Freeze in this movie. He isn't the greatest actor already, but making this movie was a big mistake with his cheesy "I'll freeze you later." line. Just a bad movie.
This one doesn't star Arnold, but he should have stayed away. This movie was complete garbage (though many people liked, that's why they made a second one) and Arnold's part served no purpose whatsoever.
