I am not sure if this is the right place to report an error - it is probably too late to amend anyway.
However, at the end they say they are going to 'St Pancreas station'.
The Pancreas is an organ. It should be "St Pancras station", the international terminal in the London town named after Saint Pancras, the boy who was beheaded by the Roman Emperor Diocletian for not renouncing Christianity.
I am assuming the text of the script autocorrected to pancreas and this was unnoticed.
