After confirmation that John Lithgow would play Hogwarts Headmaster Albus Dumbledore in the new Harry Potter series, the question naturally arose: wouldn't the involvement of such big stars as him and (rumor has it) Cillian Murphy be excessive and even harmful to the project?
The films also had stars
"It's hard to say how good this decision was in terms of filling the cast with a star cast, but I wouldn't belittle the features of the original films, which included well-known theater and film actors, like Maggie Smith and Alan Rickman, for example."
According to the expert, these actors carried with them a certain moral authority, an image of what British cinema, British theater, and the local acting tradition are.

How to attract fans?
At the same time, the question arises: will the series be able to interest viewers who grew up on the original films?
“It’s hard to say how it should be reassembled now, because the weight of the original films is so strong that the series should somehow interest viewers now, including those who grew up on the original Harry Potter and suddenly decide to watch the new project.”
Therefore, the presence of a star cast can play out well due to recognition, so that there is a task to look not only at the universe with which we are already well acquainted, but also with reference to those film projects that have been released recently, the critic concludes. At the time of the release of the films, let's be honest, the creators did not have such a way to attract attention. And this means that Warner Bros. is doing everything right.
