Philip Seymour Hoffman (Charlie Wilson's War) and Viggo Mortensen (Eastern Promises) are allegedly in talks to star in a thriller called Vanikoro for director Xavier Gens (Hitman). Gens wrote the screenplay which depicts the final expedition of a real life French explorer named La Perouse, who was shipwrecked on Vanikoro in 1788. According to BloodyDisgusting, "the ship Boussole was destroyed on a reef along with most of the crew. The second ship Astrolabe was also wrecked, but survivors salvaged enough to build a small ship and sailed away. Two survivors remained on the island into the early 1800's."
At this point, it's not clear which actor is up for what part, but we'll keep you informed as that develops. I'm sure there are a number of movie-goers still anxious for their money back after seeing Gens's Hitman, but keep in mind that Hoffman and Mortensen aren't the type to say "yes" to just every film that comes along. I'm not saying they've never been in bad films, just that they generally have good quality filters (Hoffman in particular), and we should be prepared for the possibility that Gens could surprise us all with a decent, or even quite good, thriller.
