Derry Girls star Ian McElhinney says Tommy Tiernan is 'quiet and philosophical' on set rather than playing up to the comedian role of cracking jokes in between takes.
The pair are well known and loved for their on screen report as squabbling in laws Grampa Joe (McElhinney) and Da Gerry (Tiernan) in the Channel 4 sitcom.
But offset, the pair are much more calm and collected, according to Belfast born star McElhinney, who says the popular comic is much more quiet than fans may expect.
