Flightplan

Jodie Foster is the first to acknowledge similarities between her next film and her last vehicle (2002's Panic Room). ''It's another thriller in a claustrophobic space,'' she says, ''which invites the obvious comparison.'' As a widow whose daughter vanishes on a transatlantic flight, Foster faces both a planeful of people who say her daughter was never on the flight and an air marshal (Peter Sarsgaard) who may or may not be on the up-and-up. So, more fodder for airline angst in a post-9/11 world? ''I think the movie works on that fear,'' Foster says. ''It sort of relies on it.''
