Here at IMDb, we always welcome additions to the database. If you're aware of missing information on our site, please let us know through the 'Edit page' button which is listed at the bottom of every page on our website.
From here, you can provide specific details as to the information you'd like updating and we'll take prompt measures to investigate your claim and make any necessary updates.
