horizonCAST.com has been revamped, relaunched and reincarnated (finally). We are using a new video sharing/community site tool from FLIGGO for the next round of online casting. We're hopeful that it will be a great solution (and, easier to use than our prior platform).
In "Day One" we've found Talent who submit the Registration Form without a Video; and, those who've submitted a Video without the Registration Form. It is a two step process. But, we'll try to make the interface more intuitive if we keep seeing this pattern.
It's been interesting to see how others have been using the online audition space -- now including 20th Century Fox. Having been at this for nearly three years, we know it can find new and unique Talent who might never make it to an audition in a specific City at a specific time.
