Emily Blunt has joined the cast of Rian Johnson's time-travel film, Looper, confirms Variety.
Blunt, who next appears in Gulliver's Travels and The Adjustment Bureau, will act alongside Bruce Willis (who starred in the time travel story 12 Monkeys) and Joseph Gordon-Levitt (who starred in Johnson's first film, Brick).
The early screenplay was described as "really violent and dark" by Johnson during a Brothers Bloomedit bay visit in 2008 and, according to more recent reports, will deal with a group of hitmen who receive their assignments from the future. Blunt is said to play a single mother whose son becomes a target.
Looper is set to begin production in January in Louisiana.
