Queried Wikidata with SPARQL
Just dabbling in a bit of querying Wikidata using SPARQL, as a little peek into the potential of questions we can ask the dataset

Ideally this query is supposed to fetch the list of other works that the cast of the viral show Squid Game have starred in, at least to Wikidata's knowledge (there certainly will be gaps)

I'm sure this could probably be generalized to find other works that the cast of any specified work(s) have starred in...
