The fourth installment of the seemingly never-ending Ice Age saga starts with Scrat’s perennial pursuit of the cursed acorn, which this time has world-changing consequences – a continental cataclysm that triggers the greatest adventure of all for Manny, Diego and Sid

The concept may be wearing a little thin, but that doesn’t stop this from being a highly enjoyable family film. Glorious animation, stunning set-pieces (in 3D of course) and packed full of laugh-out-loud jokes – Ice Age doesn’t show any signs of thawing out just yet.
