Making an ERD of a movie database
Can a Movie have > 1 director (like the Marvel movies and the brothers), if so this should be a many to many.

Can a movie win more than one award? If so it should be a many to many.

Can a move EVER be shot at > 1 studio? If so you need a many to many.

You solve the many-to-many by adding an intermediate table in the logical design phase. That new table has a composite key consisting of the foreign keys from the two tables participating in the relationship.

For example, for Movie and Director, you would have Move, MovieDirector, and Director. MovieDirector would have only 2 columns: MovieID and DirectorID.
