Goutte Crawler convert JSON

http://ift.tt/2rDNRY0

This link gives me a json list of title and times that the cinema is playing that specific film. I want to get that information and convert it to string however how is that possible? I have used json_decode and it says that node list is empty.

Here's my code:

function odeon(){
    $client = new Client();
    $crawler = $client->request('GET', 'http://ift.tt/2rDNRY0');
    //print $crawler->text()."\n";
    json_decode($crawler);
    print_r($crawler);
}
