And for Jamie, he’s the link to Jamie’s past in Scotland.
He’s really his father figure, as well.
Let’s talk about Jamie having to wear the red coat.

It was something that I pushed for last season.
I really wanted to see Jamie stand on the opposite side of his godfather.
And to be fighting with the people that he’s fought against the whole time?

At Culloden, Jamie was fighting for Scotland, fighting for his clan, his family and his freedom.
Now he’s completely on the opposite side.
I thought it would be quite visually arresting.
Also, Jamie is a man of honor, a man of his word.
We looked into it.
But this was more of a power play by Tyrion, wanting to test Jamie’s loyalty.
I think it really works.
I just was just blown away by how exciting the battle was.
What do you recall about shooting that scene in the woods?
I think we all really enjoyed it.
I obviously love the action stuff.
Everyone didn’t want to say goodbye to Duncan Lacroix.
He’s such a wonderful human being, a great actor.
He’s so, so good.
The scenes were actually shot over a very long time period of time.
He was around for most of the season.
Sam, I feel so stupid.
It wasn’t until I saw in the credits that that was actually Graham McTavish.
Did you get a chance to hang with him when he was there?
Yeah, it’s great, isn’t it?
I think that’s a nice little Easter egg for fans.
They wouldn’t expect that.
And obviously he’s playing an ancestor.
They tried to keep it under wraps and very quiet.
I think they gave him a different name.
I think his name was Mark Rogers on the call sheet, but everyone knew that Graham would back.
He was back a couple of days and, yeah, we hung out.
The scene in the river, what does Jamie say in Gaelic and what was that like to shoot?
It had to have been cold as hell.
It wasn’t that cold, actually.
It was a nice day in Scotland.
It was a hot summer.
He’s calling upon Dougal’s spirit to be with him and fight alongside him.
And it’s also a tradition to cut your hand?
Yeah, I guess, like a blood oath.
Obviously it’s easier to do on camera than it is in reality.
Let’s talk about what you are doing in quarantine!
You put together a 30-day social distancing work-out challenge to keep folks healthy.
We wanted to do something to help.
This was a simple way for us to hopefully bring a little lightness to people as they stay indoors.
Do you need workout equipment?
The idea was that wherever you are, you might do this.
Hopefully anyone can do these workouts.
