Will Clarke’s Altitude Film Entertainment is teaming with Subzero Film Entertainment to produce action adventure pic Big Game which has Samuel L. Jackson attached to play the president of the United States. Jalmari Helander, the Finnish director behind 2010′s Rare Exports: A Christmas Tale, makes his English-language helming debut with the pic. The story centers on a shy 13-year old boy who undergoes a test of manhood by spending a day and night alone in the wilderness. On the same night, Air Force One is shot down by terrorists and the boy discovers the president in an escape pod in the forest where the pair team up in a struggle for survival. Clarke and Andy Mayson co-produce for Altitude along with Jens Meurer of Egoli Tossell Film. Alex Garland is executive producer. Production starts in late summer and Altitude Film Sales will start pitching to buyers in Cannes. It’s also starting sales on horror thriller The Loch, co-scripted by The Woman In Black director James Watkins. Simon Duric will direct with Peter Mullan attached to star. The new take on the Loch Ness myth is set to go into production later this year.
