I am probably the only one not loving the Dutch production, but I watched a couple of video links and didn't see anything more impressive than the US productions. Of course there may be other videos that are better that I've not seen. As far as ages, when possible no smart casting director will turn down a combination of cute AND talented in the role's age range when it can be found. I disagree with 14 and 15 year old Annies, and I won't comment on a 20 year old! The US producers may seem strict, but in most cases I think they are trying to be true to the script. The child actors should reasonably represent, in real life, the ages the roles were written for or else come off less than genuine or believable in their performances. I believe adult ages can vary more, though in adult roles that is. Adults playing orphans is crazy, IMHO.
