Magnet, the newly launched genre arm of Mark Cuban and Todd Wagner’s Magnolia Pictures, has bought North American rights to Franck Vestiel’s sci-fi/horror epic “Eden Log.”

A foreign teaser trailer whipped up geek enthusiasm online late in the summer. The pic’s plot concerns a man who wakes up in total darkness at the bottom of a cave, unaware of how he got there. While pursued by a scary creature, the man tries to climb back to the Earth’s surface through a cemetery-like maze abandoned by a mysterious corporation called Eden Log.

The pic is currently in post-production.

“France has always been at the forefront of quality genre films and this will rank up there with the best of them,” said Magnolia senior VP Tom Quinn.

A North American theatrical release is planned in 2008. Among the many territories pre-sold are Japan, Korea, the U.K., Germany and Spain.
