Thanks to a tip by Matthieu, we learned that Incendiary was screened in Open Air Programme at Heineken Open Air Cinema on 21 August, 2008. Guests of the programme Coffee with... were British director Sharon Maguire and producer Andy Peterson.
See the Incendiary write up here. Also, this page of the program has a new image of Michelle Williams. There is a write up of Sharon Maguire in Bosnian/Croatian, here.
For some reason, the message boards at IMDb incorrectly state that Incendiary was shown on 15 August, but as the link above shows, it was really shown on 21 August.
