IGN: So, you’ve mentioned that you did not know Amy was River’s mother until you filmed the big reveal episode. What was your reaction when you found out?
Gillan: I honestly couldn’t believe it. I was shocked. I was so excited by it, because it opens so many more doors, rather than closing a storyline, as Steven [Moffatt] has mentioned. And also I felt quite privileged to be such an important part of the whole storyline. Little did we know when we saw that wedding dress hanging in Amy’s bedroom in the first episode that that wedding was going to inevitably going to lead to the birth of River Song. It’s mad!
IGN: Will we be getting more insight into Amy herself soon?
Gillan: You do. Yeah, actually we go back and see Amy as a little girl. We see her as a 16 year old teenager and then we see how she and Rory get together around 18. The little girl is played by my cousin, who played young Amy in the first episode, and then I got to play a 16 year old and an 18 year old Amy – through the ages!
