Those still scratching their heads over the conclusion of Christopher Nolan's Inception might want to point their web browsers to Clothes on Film. The site recently conducted a fairly enlightening Q&A with the film's costume designer, Jeffrey Kurland.
"On to the second part of your question," Kurland responded after the interviewer said the Cobb's children had on the same clothes in the dream and the final scene," the children's clothing is different in the final scene... look again..."
So, if Cobb's kids had on new threads does that mean he made it home or did they simply discover a JC Penny's somewhere in limbo? Speculate in the comments.
