Watched the 2006 short film on Dido Belle?

There's a dramatic short film on IMDb that was apparently workshopped at Battersea Arts Centre back in 2006 (via the Battersea Writers' Group script development program).

Click on the VIDEOS listing and watch the short film (4:50, including 55 seconds of credits).

I'm interested in others' thoughts on this short. I wonder what kind of research they did, in characterizing the relationship between Dido and her cousin that way? (This depiction is at odds with the portrayal in Belle, from what I've seen in the trailer.)

There's also a 58-second trailer, which seems somewhat redundant, considering the extremely short length of the film.
