Another angle: the user might be referring to a fan-made sequel or a web series. "Suburban Secrets 2004" exists; maybe a fan project in 2021 with a different title part. The encoded parts could be a red herring, or maybe a play on the title. The user could be referring to a puzzle or a code within the film. Alternatively, the user might have made a mistake in typing the title. Maybe "mshahdt" should be "Suburban Secrets" and "mtrjm fydyw" are incorrect. Let me check if "2004" is the original release and "2021" a remake, but I can't find information on that. Maybe the user is referring to a specific scene or a reference in a film. Without more context, it's challenging. The best approach is to explain what is known about "Suburban Secrets 2004" and note the encoded parts without clear meaning, suggesting possible ciphers. Also, mention that if the user can provide more details or clarify the encrypted parts, a more accurate answer can be given. Maybe there's an inside joke or a specific reference I'm missing.
