Just watched this on BBC One, and have to say it was ok. Much better than alot of rubbish that's been coming out recently and makes a change to show a different film apart from Sixth Sense and Die Hard all the time.
One thing came to my mind though, why didn't Sandra Bullock's character just ring the US version of '118 118' and track Reeve's character down? Would have saved a lot of hassle!?
