**strokes chin and wonders how much said film is going to encourage Middle Aged Mums In Leggings/jeans/other-normal-clothes to cycle more**
or whether it might reinforce stereotypes
etc
The trailer seemed to suggest it was a reasonably sympathetic view of the diversity(!) within the target demographic of middle aged white men who enjoy riding bikes as a sporting / social activity. As such it might break down a few stereotypes of that group, in as much as anyone who isn't a Cyclist is going to watch it in the first place.
I doubt it'll do anything to encourage anyone else to ride a bike, but then neither would that film about Graeme Obree trying to break the HPV record, or that excellent play about the life of Beryl Burton.
http://bicyclethefilm.com/ was pleasingly inclusive, and much more encouraging, but it was about a different subject.
Personally, I reckon anything that's about ordinary people cycling (for whatever reason) makes a refreshing change from yet another sports star biography.
