That title has just been submitted to the database, and is in the process of being added. It can take a couple of days from when you first find the title with the search engine before the title is actually clickable without seeing a 404 error page, and even more days before all the data that was added in the original submission is visible on the page.
You should give it at least a week before you try to edit it and add more cast and crew. If you added the cast and crew in the original submission it will probably appear by then too.
