Final answer:
The statement is false, as commercial cinema does not solely use restricted narration, and both third-person limited and omniscient narratives are employed to tell stories in films.
Step-by-step explanation:
The statement that the most common type of storytelling in commercial cinema is restricted narration, where we know only as much as a given character, is false. Different narrative techniques are employed in filmmaking, including both third-person limited and third-person omniscient perspectives.
Third-person limited narration confines the audience to the knowledge of one character, limiting the point of view and potentially creating bias. Conversely, third-person omniscient narration provides a more comprehensive understanding of the story by showcasing multiple characters' perspectives and revealing all the facts.
