Julianne Moore lends her mad-housewife persona to this outlandish but gripping paranoid thriller by Joseph Ruben (The Good Son, Sleeping With the Enemy). A flinty Brooklyn mother whose son has died in a plane crash awakens one morning to find that every memento of the child has vanished; her husband (Anthony Edwards) and shrink (Gary Sinise) tell her she's manufactured memories of a boy who never existed, but she refuses to believe them. The solution to this mystery will tax even the most credulous viewer, but Ruben delivers some deliciously weird shocks along the way. With Dominic West. PG-13, 89 min.
