I wish there were more actresses out there like Pam Grier. A very pretty face, a wonderful body, a tough attitude and surprisingly mature acting for a woman who was, when this "Arena" was made, only 24 years old. And Margaret Markov, her co-star here, is not far behind in any of those categories. The biggest virtue of this film are those two characters - strong, well-defined, acted with conviction. Others have compared the "Arena" with Roger Corman's WIP flicks, but the treatment of the subjects here is much more thoughtful and non-exploitative. As for the actual fight scenes, considering that most of these women probably had not touched a sword before in their lives, they did a fairly good job. Too bad the DVD is full-screen, which damages the compositions severely. (**1/2)
