Why are actors still missing from the cast of a new film?

If this has just been added and the people were in the submission then you need to wait. Credits get slotted in over a few days (up to a week or so) as the relevant pages get rebuilt, not all at the same time.

If it has been a couple of weeks after the submission was accepted (well the main entry for the film was created), then it'd be a good idea to include the submission ID so staff can check if there is a problem.

Hello alonsoairaldi,

As Emperor mentions, when a new title is added to the database it can take up to two extra weeks for all the information to appear as different sections of the database are updated at different times (and new names require further research).

You can check when different sections of the site were last updated here: http://www.imdb.com/czone/times

Thanks Emperor for you help!

Looked recently at the full cast page of a recent film called "American Made" because when I watched it, the name Ronald Reagan as actor did not appear in the end texts but I had identified this actor on screen (more precisely Ronald Reagan Senior). Turned out that his name was on uncredited list, but not the name of the woman I believe sat on his side when two people, a man and a woman, spoke there against drugs at the White House. I believe that the actress who sat there is most likely Nancy Davis, but her name does not appear in the uncredited cast...however, I'm not 100% sure of this.
