How do you unwind at the weekend?
Grimes: I absolutely adore the weekend and love lighting an early evening fire in our home in Donaghmore near Dungannon. We have teenage sons so there's a bit of taxiing about and I go for walks with our Kerry blue terrier called Torai. Not Tory, it's an old Irish name. I love music and on Spotify have everything from Tom Waits to Hot Chip.
McKee: I watch an awful lot of sport: football, rugby, anything going. But my weekend plans for sport on TV don't always succeed – there are other people in this house.
What do you recall of weekends growing up?
Grimes: My uncle and my dad both had grocery shops so weekends were slavery. It was child labour and we were paid in ice cream. Lots and lots of ice cream.
McKee: Weekends growing up in Coleraine were always about seeing family – Granny, grandas, uncles. We went to St Patrick's Sunday School. Conor and I are a mixed marriage and we should be getting some sort of grant.
Friday night or Saturday night?
Grimes: I'm Saturday night. When you do comedy, Saturday's the big night and I am happy as a cow at milking time. I love Friday night too but when I'm not working, there's too much anticipation.
McKee: I'm a Friday night person. I have to say a couple of pints then are just the most gorgeous thing. When in rehearsals, it's so good to shift gear and head for the Oak Room – aka God's waiting room – in The Errigle.
Do you have a must-listen to radio show at weekends?
Grimes: I love 6 Music and Cerys Matthews. At one stage the BBC were going to scrap it and I was part of the campaign to save it, with a petition saying 'Do not under any circumstances get rid of it.' It's a really good, eclectic programme.
McKee: It's Belfast's own Colin Murray on Radio 5 Live – it's a comedy sports programme and it's fab.
Weekend TV/box set?
Grimes: I don't watch box sets, haven't seen Game of Thrones although I hear it's great.
McKee: At the moment it's Dark Material which is appointment TV.
Favourite eatery or is it a takeaway?
Grimes: Our favourite restaurant is The Brewer's House in Donaghmore, which is beautiful but closed at the minute. It's a gastro pub and they do a brilliant early bird menu with steak and a glass of wine.
McKee: L'Etoile on the Ormeau Road in Belfast. I start with the mussels and you can't really beat their well-aged steak.
Is Sunday still special?
Grimes: Yeah, we go to Mass and in the afternoon, take the boys to see Granny and Granda. We have a cup of tea and a catch-up. Sun daydinner is a roast and spuds and I cook but am not as good as I'd like to be.
McKee: Yeah, it is – people have more room.
How do you feel on Sunday night about Monday morning:
Grimes: Sunday night is about my favourite night. Partly because we usually have Monday off but also because I love what I do. I always wanted to go into the business and attended the National Youth Theatre in London with Dan(iel) Craig and Tom Hollander, one of the best actors I've ever seen.
McKee: Quite often I haven't done my homework.
