Crystal Lake | John le Carré: A New Life | Ellie & Natasia

It's a Must Watch duo rather than a trio this week, as Scott Bryan joins Naga Munchetty to review the latest TV.

First up, on Sky, Crystal lake is the prequel series to the Friday the 13th franchise, showing how Jason's mum Pamela Voorhees (Linda Cardellini) became a bloodthirsty killer.

There's the second series of the BBC sketch comedy Ellie & Natasia, starring comedians Ellie White and Natasia Demetriou, delivering more of their surreal sketch comedy. It's available on iPlayer.

Finally, the spy novel legend David Cornwell A.K.A. John le Carré has a new documentary examining his life and works on Sky Arts, hearing from those who knew him personally including his biographer and contemporaries.

Also, we read your emails, recommendations and Scott's Must Watch pick of the week.
