Filming of Secret Life in December 2006?

I found an interview of Holly Aird, who plays "Emma" in Secret Life.  The interview was dated December 17, 2006.  In it she was asked:  It appears that although filming of Secret Life may have started in October 2006, it also extended into December and possibly beyond.

Do you have any further acting projects lined up?

I have recently finished doing a play with The Royal Shakespeare Company and I start filming next week on a Channel 4 film called 'Secret Life'.

The interview can be found here.
