Capitol Films has picked up Irish director Paddy Breathnach’s upcoming horror movie Shrooms for worldwide sale, according to Variety. The pic, which starts shooting March 20, is about five American students on a camping trip in Ireland. They get high on magic mushrooms and are haunted by ghosts, which may or may not be a figment of their drug-addled imaginations. Script is by Pearse Elliott (“The Mighty Celt”). Producers are Paddy McDonald and Robert Walpole, with Gail Egan (“The Constant Gardener”) exec producing.
