Dornan and Anderson both returned to Belfast to reprise their roles as the battle between Detective Superintendent Gibson and Paul Spector reaches its terrifying conclusion in Allan Cubitt’s intense psychological thriller.
Audiences were left reeling at the end of series two as Spector, critically injured in an ambush, lay bleeding in the arms of Gibson.
Moments before, the investigator thought she had him and now it appears as though she is losing him.
Fans of the programme were sent into overdrive when they spotted Dornan around Belfast during filming.
Today Gillian Anderson was filming outside The Merchant Hotel in Belfast along with series regular John Lynch.
There are some newcomers to the programme time around as Krister Henriksson (Wallander), Aidan McArdle (Mr Selfridge), Ruth Bradley (Humans), Aisling Bea (Trollied) and Richard Coyle (Crossbones) are all cast.
Speaking previously writer Allan Cubitt said he is "thrilled" to begin Series 3 and while he didn't want to give anything away about the ending - he suggested this may not be the last series we see of The Fall - leaving the door open for more.
He said: "Obviously I don't want to give anything away about how the third series will end but I can say that I am looking forward to working with both Gillian and Jamie again in the near future."
