But how to handle proper nouns like "Shah Rukh Khan" - they should remain untouched. Words like "film", "action-packed", "thriller", etc., need to be replaced with three alternatives. I need to generate three suitable synonyms for each non-proper noun word.

I need to check each word for possible three valid alternatives and format them correctly. Also, ensure that words with multiple meanings are appropriately handled. For example, "Full HD" should stay as is in terms of structure but the alternatives might vary.

I need to check each substitution to ensure they make sense in context and are grammatically correct. Some words like "entertainment industry" might have alternatives but should fit. For example, "entertainment sector" could work. Also, need to avoid repetition of the same word in the choices if possible, but sometimes it's necessary if there's no exact synonym. For instance, "thriller" might have "suspense" as an alternative but in the context, sometimes "thriller" is the best fit.
