Could a sequel be made?
Box office performance aside, the future of all the characters intrigues me.
Lara & John are by no means 'free' - they're living a life looking over their shoulders & are bound to run out of money sooner or later. Despite the button probably being gone for good the detective knows deep down she's innocent. It would be interesting to see the family return fed up with life on the run & determined to prove her innocence once & for all.
