Universal took the UK, Australia, Spain, Latin America and New Zealand to Walden Media's family drama Nim's Island starring Gerard Butler, Jodie Foster and Abigail Breslin.
Meanwhile Entertainment is believed to have swooped on UK rights to City Of Ember, a tale of teenage heroism that Walden is co-producing with Tom Hanks and Gary Goetzman's Playtone Productions.
Both titles are among the hottest properties in a market in which buyers are scrambling to find marketable English-language fare.
Summit also closed a two-picture deal with Momentum Pictures for The Baader-Meinhof Complex and the Summit-Manderlay Pictures co-production Get Some.
The move confirms the UK's burgeoning reputation as the most aggressive buyers outside the US.
Summit International president David Garrett negotiated the deal with Momentum's director of acquisitions Robert Walak.
Both projects are in pre-production andset for a 2008 release. Uli Edel will direct The Baader-Meinhof Complex, which chronicles the German terrorist group's wave of robberies, kidnapping and assassinations during the 1970s.
Get Some is styled as a teenage Fight Club that Jeff Wadlow is directing and Summit chief Patrick Wachsbergeris producing with Erik Feig, Craig Baumgarten, and David Zelon.
'Momentum are a great team and always bring aninventive angle to their marketing strategy,' Garrett said. 'They always manage to getthe very best out of every film they release and it is a pleasure to becontinuing our relationship with them.'
