A fix for (what I assume this was) was pushed 5 or so minutes ago. Seems to be working for me. Is it for you?

Not yet.

It works for me (have registred same issue) but page seems a little bit different now, there is no "pen" to click to add overview (description of the movie) there is edit to the right you have to click.

there is no "pen" to click to add overview

Yes, we rolled out a new edit interface this afternoon. Click the "edit" link now.

The page is still working ok for me though, befuddled, can you make sure to shift-refresh and let me know. If it's still throwing the error what URL are you on and what are you trying to do?
