Harry Potter's spell continues at UK box office
Though Sandra Bullock's new rom-com made it to the top of the chart across the pond in the US, it failed to take on the magical spell cast by the sixth Potter film on this side of the Atlantic.
Animated sequel Ice Age: Dawn of the Dinosaurs slipped one place to number three, pushing controversial new Sacha Baron Cohen flick Bruno into fourth.
Surprise comedy hit of the year The Hangover narrowly stayed in the top half of the ten big hitters at number five, while last week's fifth-placed film Transformers: Revenge of the Fallen dropped to number six.
Despite being unable to topple the mighty Harry Potter, The Proposal still proved to be Sandra's most successful UK box office opening ever.
She has recently finished filming All About Steve with The Hangover's Bradley Cooper, which is due for release in January 2010.
