Doctor Who: 14 Cool Details Revealed In Steven Moffat's Eleventh Hour Commentary
12. Karen Gillan And Caitlin Blackwood Met For The First Time On The Doctor Who Set
After that shot of the house's exterior, we cut to its interior to meet little Amelia Pond, who is played by Caitlin Blackwood - the cousin of Karen Gillan.
Bizarrely though, despite the two of them being relatives, they didn't actually meet until they bumped into each other on the Doctor Who set - something that Willis reveals early in the commentary.
Apparently, this is because Blackwood was raised in Northern Ireland, while Gillan grew up in Scotland.
