In Neo4J Movie database, how to find an actor's co-actors in all movie he/she acted in

Question

I want to find all movies an actor acted in, and for each film retrieved, find his/her costars in that movie. How to write Cypher for this query?

Answer 1

Here is the Cypher to find the list of movies Tom Hanks acted in, and for each film retrieved, it also finds Tom's co-actors

MATCH (tom:Person {name:"Tom Hanks"})-[:ACTED_IN]->(films)<-[:ACTED_IN]-(coActors)
RETURN tom.name, films.title, coActors.name;

The above query will result like this:

╒═══════════╤════════════════════════╤════════════════════════╕
│"tom.name" │"films.title"           │"coActors.name"         │
