nested queries and info

I have a query that looks like this:

```
movies {
name
actors {
firstname
lastname
movies {
name
}
}
}
```
at the moment it is very easy for me to use the dataloader to query the actors of each movie but I have two problems:
1. how do I use the dataloader to query the children of the children? In my case the movies of an actor
2. how can I pass the parsed info data (so I know what fields are queried) to the dataloader, without reparsing the info, because as you know, the children-resolver is invoked for each parent

would be nice to see a simple example
thanks in advanced!
