Not really. 'Interview with a Vampire' focuses on complex character dynamics and supernatural elements rather than being centered around a gay theme specifically.
One interesting plotline could be the exploration of the complex relationship between two male vampires in a homoerotic context. For example, how they deal with their immortality together, facing the challenges of vampire society which might not be fully accepting of their relationship. It could also involve their shared experiences of hunting, and how they navigate their feelings while being creatures of the night.
Armand is also a character that might be paired with others. For instance, he could be paired with a new, original male character created in the fanfiction. Armand's long history and his own brand of vampiric allure can make for an exciting relationship when combined with another male character, whether it's a fellow vampire or a human turned vampire.
One interesting plot could be a different origin story for the vampires. Maybe they were created not just by a single vampire but a group of ancient beings. Another plot could be a love story between a human and a vampire that defies the normal rules of their relationship in the original story. And perhaps a plot where vampires are trying to co - exist with humans in a more open way.
Lestat is often a very popular character. His charm and his complex personality make him a great subject for fanfiction. Louis is also popular as he is one of the main characters in the original story and has a lot of room for further exploration in fanfiction. Claudia can be a popular character too, especially when writers explore her relationship with Louis and Lestat from different angles.
One interesting idea could be exploring the backstories of the minor characters more deeply. In the fanfiction, they might give a detailed account of how a particular vampire was turned and what their life was like before. Another idea could be alternative relationships between the characters. For example, a fanfic might explore a different kind of bond between Louis and Lestat that wasn't fully shown in the show.
Louis and Lestat are likely to be very popular. They are the central characters in the original work, and in fanfiction, people would love to explore their relationship further. Writers might delve into their complex feelings for each other, be it love, hate, or a mixture of both.
One interesting theme is the exploration of the complex relationship between the vampires in a more homoerotic context. It often delves into their eternal bond and how it can be interpreted in a romantic and sexual way.
Lestat and Louis are often a very popular pairing. Their relationship in the original work is already complex and full of tension, which makes it ripe for slash interpretations. Fans like to explore their deeper emotional and physical connection in fanfiction.
