That doesn't quite work.  You need to flatten the result of each zip, as posted earlier:

        movies.values.transpose.map{|a|Hash[*movies.keys.zip(a).flatten]}

Your version yields this on the given input, which is not quite right:

[{["title", "ciccio"]=>["id", "3"], ["description", "1"]=>["insert_date", "2005-10-19"]}, 
 {["description", ""]=>["insert_date", "2005-10-20"], ["title", "test"]=>["id", "4"]}, 
 {["title", "ciccio panza"]=>["id", "1"], ["description", "hey?"]=>["insert_date", "2005-10-18"]}]

In fact, it would raise an exception if there didn't happen to be an even number of fields per 
record.
