Definitely not. Comic books have their own unique style and format. They rely on sequential art and can have more freedom in terms of panel layout and page design. Screenplays, on the other hand, are structured to provide specific instructions for actors, directors, and other crew members in a linear format for a live-action production.
No, they aren't. Comic books can play with the layout and presentation of the story visually. Screenplays are more constrained by the practicalities of filming and have to follow certain conventions for scene transitions and dialogue delivery.
