Hi Boldra,

with some minor modifications your script works as intended:

package TestDB::Scene {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('scenes');
    __PACKAGE__->add_columns(qw<title time description film>);
    __PACKAGE__->set_primary_key(qw<time>);
};

package TestDB::Film {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('movies');
    __PACKAGE__->add_columns(qw<title director>);
    __PACKAGE__->set_primary_key(qw<title>);
    __PACKAGE__->has_many( scenes => 'TestDB::Scene', 'time' );
};

package TestDB::Director {
    use parent 'DBIx::Class::Core';

    __PACKAGE__->table('directors');
    __PACKAGE__->add_columns(qw<name>);
    __PACKAGE__->set_primary_key(qw<name>);

    __PACKAGE__->has_many( movies => 'TestDB::Film', 'title' );
};

package TestDB {
    use parent 'DBIx::Class::Schema';
    __PACKAGE__->load_classes(qw<Film Director Scene>);
};

package main {
    use Modern::Perl;

    main: {
        my $schema = deploy_new_to_temp_file();

        my $rs         = $schema->resultset('Director');
        my @population = (
            {
                name    => "Lesly Tack",
                movies => [
                    {
                        title  => 'Alligator',
                        director => '#Lesly Tack',
                        scenes => [
                            {
                                title => '1st swamp pan',
                                time  => '05:36-12:01',
                                description => 'Murder in a Swamp base
+d Collection',
                                film => '#Alligator',
                            },
                        ]
                    }
                ]
            }
        );
        my @sources = $schema->sources;
        # for my $source (@sources)   {
            # print "Table: ", $source, "\n";
            # print "Columns: ", (join ", ", $schema->source($source)-
+>columns), "\n";
            # print "Relationships: ", $schema->source($source)->relat
+ionships, "\n";
        # }
        $rs->populate( \@population );
    }

    sub deploy_new_to_temp_file {
        my $schema = TestDB->connect('dbi:SQLite:dbname=test.db');
        $schema->deploy( { add_drop_table => 1 } );
        return $schema;
    }
};

But I think, you have to redesign your database a little, because the columns 'director' in table movies and 'film' in table scenes seem redundant.
