I don't think it'd hurt to प्रकाशित करे this matter as an लेख too... Seeing to how blind so many people are to this in the name of "It didn't go like that in the books!!!" So, let us look into the books to see if it might make sense.
But before that - let me explain:
In the film; The producer of the film in F.A.Q at Warner Bros's QOTD site:
"Marius makes Lestat for the sake of economy. It happens to work extremely well from a character-motivation point of view.”
I know! I agree. It really does.
”We changed who made Lestat because we couldn't keep every character, and Marius is a terrific substitute.”...
