If you google Hamish movie (film?) or Hamish Henderson (or the director's name Robbie Fraser) you should find a list of places it is going to be touring soon - - tho I suspect they might all be in Scotland?
However at the Q&A after the premiere I think they mentioned film festivals too -- so worth keeping your eyes open? Sending in requests?!

I missed the other premiered film which features Sheila Stewart: Where you're meant to be by Aidan Moffat of Arab Strap (a group apparently) However it too is going on tour so I shall book myself a ticket for March / April.
All the reports I've hear of both films have been great. I certainly enjoyed Hamish
