Changing my known for screenplay page

Writerdude: Assuming you are who I think you are (you can reveal your name here if you want, or not if you don't want to), "Deceptive Vows" is your only credit listed on IMDb, so there is nothing else you can be known for yet. You would need to get "Predator in the Clubhouse" listed as a new title on IMDb (using the form that starts at https://contribute.imdb.com/updates/edit?update=title and continues on succeeding screens) before you could be "known for" that. That said, once "Predator in the Clubhouse" is listed in your credits, you can change your "known for" titles (to choose only one of those titles as what you are "known for") if you are an IMDbPro subscriber. See https://help.imdb.com/article/imdbpro/manage-your-imdb-page/manage-your-filmography/GH8XTYSWKU2P96TA# for details about that. If you are talking about removing "Deceptive Vows" from the IMDb altogether, you can request that but only if the project has been cancelled altogether and is never going to be produced. You would need to start from the project's page on IMDbPro and click "Edit page". Then select "Other Corrections", then "Title Deletion", and follow the instructions from there. You will need to provide an explanation that you are the writer and that the project has been cancelled, and provide evidence of that. I hope this helps.
