“Six Feet Under” actor Jeremy Sisto is starring in Sony’s “Population 436,” which Michelle MacLaren will direct. Limp Bizkit singer Fred Durst will also star. Shooting begins in Winnipeg in mid-June. The psychological thriller concerns an idyllic town whose population of 436 has remained unchanged for 100 years. Sent out to find the reason for this consistency, census-taker Steve Kady (Sisto) finds that something much more sinister may be at hand.
