I ask because I know that there can be a great deal of regional variety in dialogue (I'm thinking dialects here), so if a movie or show takes place in Rome, for example, as a new learner I may not be 100% clued in that they are speaking in the Roman dialectical variant of the language, or whether it's standard Italian.
An example question could be "Is the Italian used in La Vita è Bella standard Italian or does it incorporate any dialects that I'd need to be aware of?"
Are questions of these types on-topic?
