Welcome to my all new DVD Thriller, which, as the name suggests, is all about thrills at the wheel. Aston Martin’s gentleman thug, the DBS, takes on its rivals from Italy.

In the 1950s, Tab Hunter was number one at the box office and number one on the music charts and was Hollywood’s most sought-after young star. Natalie Wood, Debbie Reynolds and Sophia Loren were just a few of the actresses he was romantically linked to. He was America’s Boy Next Door and nothing, it seemed, could damage Tab Hunter’s career. Nothing, that is, except for the fact that Tab Hunter was secretly gay. Now, the secret is out.

A profoundly personal voyage into the complexity, fragility and wonder of the human brain, after Lotje Sodderland miraculously survives a hemorrhagic stroke and finds herself starting again in an alien world, bereft of language and logic.

When NATO troops withdrew from Afghanistan, the Afghan National Army (ANA) took over control of Helmand Province, an extremely dangerous region where attacks by Taliban fighters are the order of the day. Security, much less peace, would seem to be unattainable; it is even difficult to find a common language in a country where everyone mistrusts each other.

They cannot fight a war with the equipment left behind by the ISAF.
