Kelly Hu in Scorpion King 1. This whole series in general loves dressing their female leads in midriff-revealing outfits, but for the most part of SK1, Kelly wears stuff like this:
Which, although certainly revealing and sexy, isn't quite within the scope of this forum.
Here are some screencaps from when she does bare her midriff in the movie. There's also a couple shots of amazon extras there.
Unfortunately, when I took these screencaps, I used a video player that makes them slightly more green than they actually are.
Is Scorpion King 1 worth watching for anything besides Kelly Hu? I'd say yes. It's nothing particularly special, but it's a decent sword-and-sandals adventure.
More shots from Scorpion King movies: Kelly Hu in SK1 (good), Karen David in SK2 (meh), Natalie Becker in SK2 (minimal amount of content), Krystal Vee in SK3 (good), Selina Lo in SK3 (okay), Ellen Hollman in SK4 (phenomenal!)
