User blog comment:Mr. Joshamee Gibbs/P5 : Philip Swift's return?/@comment-1140008-20120621004536/@comment-1984959-20120621012504

I couldn't agree more. If Syrena was portrayed by any of the American women, I can understand fussing over her performance. But as OST was Astrid's first English-speaking film, I can understand why she wasn't "the female prodigy" of the films. All in all, I can say without a doubt that Astrid fit the role visually - nothing sensual about it, mind you, just...Stirrings' lol xD(but seriously though she did fit the Syrena role, IMO at least).

I agree with Mr. Joshamee Gibbs below that it would be hard to work out, since she's a mermaid.
 * As long as P5 goes strictly near water-based realms, or water in general, Syrena should be able to fit in the story(it's the Caribbean, remember? lol). But I will say though that she could have the ability to walk...not sure if anyone could tell from the film, as I didn't see much discussion of it, but Syrena couldn't walk because of Philip stabbing her fin.(all from the script ;))
 * Though I think what MJB was talking about was that it would be hard to work out putting Philip alone in P5(as he's now tied to Syrena in terms of the POTC fanbase).
