British film-maker Guy Ritchie insists Kabbalah is a science rather than a religion.

The Snatch director first developed an interest in Kabbalah when he married his wife Madonna in 2000 - and he aims to shed light on the mystical offshoot of Judaism in a forthcoming documentary he is making.

And Ritchie is adamant he would have no interest in incorporating Kabbalah into his life if it was a religion, because he believes doctrinal religions are a "con".

He says, "Kabbalah is the study of sciences - it is not a religion. I don't follow it as a religion. Anything you do follow as a religion is a con."
