Eat your heart out Tom Cruise. So what if you scaled the world’s tallest building for M:I-4? Melissa George’s gutsy mountaineer shows just as much derring-do as she leaps from crag to cranny in this breathless thriller.
Along with Ed Speleers (Eragon), she’s chased by sniper kidnappers in the Scottish Highlands, which leads to all manner of impressive, gravity-defying scraps.
Equally impressive are this disc’s numerous extras, including a 70-minute Making Of and a look at director Julian Gilbey attempting to conquer alps The Matterhorn and The Eiger. Daring stuff.
