Hello, If it's a name page on IMdB it cannot be deleted. IMdB is a database of film/entertainment and contains all factual info on films, tv series etc.. If it's a user profile- that can be deleted. A name page has nm2106835 (example) in the url whereas a user profile has ur0000000 in the url.
If you have a name page on IMdB with some incorrect credits, those can be fixed. The members here are very skilled at getting those edits made so if you need help with that, posting a link to the name page & which credits are incorrect would be step one for the folks here to assist you.
