I just saw it on HBO. I don't know if anyone has mentioned this but it's so obvious that Neeson, Jansen and the daughter filmed their parts at different times, not with each other.The only scene Neeson and Jansen did together was the final rescue scene. Just look for the over the shoulder shots, odd lighting changes, shots with just one actor talking to the other off screen. They stitch together some shots where the actors appear to face each other. I wonder if they used two sets or green screen.
