Tron: Legacy saw off the bad weather and the threat of the Dawn Treader to debut top of the UK box office.

Disney’s long-awaited sequel took $3.1m (£2.0m) from 454 locations for a week-high location average of $6,571 (£4,341). It was a solid, if unspectacular, start for the sci-fi adventure, but it was no doubt hindered by the severe weather conditions experienced across the UK over the weekend (some of the worst conditions reported in over 100 years.)

The snow affected not just the launch of Tron: Legacy but also the chart as a whole with the combined top 20 gross around $2.3m (£1.5m) down on last week’s top 20 take of $13.0m (£8.4m).

Fox’s The Chronicles Of Narnia: The Voyage Of The Dawn Treader suffered a 50% week-on-week drop in its second weekend after grossing $1.9m (£1.2m) for $7.4m (£4.9m) overall.

It now requires a significant boost from the upcoming school holidays to challenge Prince Caspian’s final haul of $11.9m (£7.7m), but must hold off the family-friendly threat of Fox’s Gulliver’s Travels in the process.

Another film looking for a boost in the coming weeks will be Harry Potter And The Deathly Hallows: Part 1. The Warner Bros. fantasy now stands at $69.1m (£44.4m) overall after conjuring up a further $1.4m (£875,898) and is just $2.4m (£1.7m) shy of overtaking Prisoner Of Azkaban’s final tally of $71.5m (£46.1m), but it seems an unlikely prospect to overtake Philosopher’s Stone epic haul of $102.5m (£66.1m).

Sony’s Burlesque was the week’s second highest new entry after enticing $656,191 (£421,931) from its 341 locations to chart sixth. By comparison, Rob Marshall’s Nine grossed $417,938 (£269,447) in its first weekend of wide release (it was released in the West End a week earlier) although that was from significantly fewer locations (123).

In a busy week for new releases, there were three other debuts in the top 20. Entertainment’s Animals United and Lionsgate’s Fred: The Movie charted at seventh and eighth after taking $478,086 (£307,409) and $399,896 (£257,133) respectively, but it was Momentum’s Catfish that opened most impressively out of the trio.

The Sundance hit documentary took an admirable $43,633 (£28,056) from just 15 locations to record this week’s fourth-highest screen average of $2,909 (£1,870), behind Tron, Narnia and the re-release of the 1940 romantic comedy The Shop Around The Corner.

This week sees saturation releases for Paramount’s threequel Little Fockers, Fox’s Gulliver’s Travels, eOne’s The Way Back and Entertainment’s Arthur And His Greatest Adventure.
