strategy of the Hollywood musical

We have discussed that a major strategy of the Hollywood musical, as a
vehicle of entertainment, is to present a Utopian world – an image of
something better than the realities of every-day existence that we can
escape to, and where our wishes will be fulfilled.
Is this the same strategy used in both films? Or is it different?
Discuss in relation to the settings of both films, and the contexts in
which they were each made.
