Stuart "Charmed" Gillard will direct for producer Robert Halmi.
Located millennia in the future, the 'Riverworld' is an Earth-like planet whose surface has been 'terraformed' to consist of one long river-valley, with an average depth of 1.5 miles, shallow near the shore then plunging to enormous depths towards the channel. The banks expand into wide plains then climb into jagged hills before a sheerly impenetrable mountain ridge, taller than the Himalayas. While the valley averages 9 miles in width, the river is 20 million miles long.
