The document discusses continuity of time setting through props and costumes in film opening sequences, such as using sepia tones for Gladiator to indicate a historical setting. It also analyzes the author's own opening sequence for a film called "Repressed Memories," noting the use of techniques like jump cuts, cross dissolves, and old English font to establish the 16th century time period, while acknowledging some elements may not show full continuity. Examples from other films like Gladiator and Troy are provided.
