I now have some confirmed screening dates and times for Somers Town at the Watershed in Bristol. Also worth noting, the film is definitely being shown here for two whole weeks, and it will be shown digitally.
From Friday 22nd August until Sunday 31st August, Somers Town is on everyday at: 15.00 - 18.10 - 20.10
(No 18.10 screening on Tuesday 26th)
It continues until the 4th September, but the September times are not confirmed yet.
