Robin Hood was the top draw at the international box office again this weekend, though it was challenged in some markets by debutant Prince of Persia: The Sands of Time. Shrek Forever After, meanwhile, made a huge international start in Russia.

Losing strength after its powerful debut last weekend, Robin Hood grossed $30m from 7,157 dates in 58 territories (the only new opening was in Vietnam), distributor Universal/UPI estimated. The second-weekend tally pushed the action adventure’s international total to $125m.

In the UK, Robin grossed an estimated $2.1m from 538 dates (for a 10-day total of $13.3m), ceding top spot on the local chart to British opener Streetdance.

In Germany, Robin took $1.4m from 667 dates (for an 11-day total of $8.7m), coming in second to Prince of Persia.

Robin stayed top in France, with $2.6m from 648 (12-day total $10.7m), and Australia, with $3.1m from 496 dates (total $9.7m).

In Korea it was off only 12%, grossing $3.2m from 256 (11-day total $7.8m).

It retained top spot in Mexico with $1.9m from 496 (10-day total $6.2m) and held on at number two in Brazil with $1.6m from 268, off just 34%.

Prince of Persia: The Sands of Time began its international rollout a week ahead of its US opening and grossed an estimated $18m from 4,125 screens, ranking number one in 18 out of 19 territories. Distributor Walt Disney Studios Motion Pictures International (WDSMPI) said the opening was 5% ahead of National Treasure’s for the same group of markets but 13% behind Iron Man’s.

The Jerry Bruckheimer-produced fantasy adventure with Jake Gyllenhaal and Gemma Arterton starring ruled in Spain with an estimated $3m from 560 theatres, in Germany with $2.8m from 650, and in Italy with $2.8m from 525.

In the UK, Prince took an estimated $2.1m from 585 theatres, putting it in a close race with Robin Hood for second place on the local box office chart.

Prince expands to another 30 markets next weekend day and date with its domestic launch.

Shrek Forever After opened in a handful of international markets simultaneous with its relatively soft domestic launch and grossed an impressive $26m from 1,236 locations, said distributor Paramount/PPI.

The fourth installment - and first in 3D - of DreamWorks Animation’s powerful animated franchise took an outstanding $20m from 700 locations in Russia. That, said PPI, made it the territory’s biggest opener of all time, 1% ahead of Avatar, 18% ahead of Ice Age 3 and 65% ahead of Shrek The Third.

In Ukraine, Forever After grossed a chart-topping $1.3m from 92 locations (22% more than Shrek the Third and 8% more than Ice Age 3).
