'There's not much emotional drama'

The 47-year-old actor says the artists treat their exit like just another professional decision and look forward to other jobs, reported Men's Health magazine.

"There have been some dinners, but when you follow a show and you love the characters and they die, it becomes a big deal because you've invested in these people. When you work on something as an actor, and especially when you've done this for as long as Diana (Rigg) has, that's just the nature of what you do.

You do a job and then it ends and then you do another job. Yeah, it can be sad if you've had a great relationship, but you'll meet again later on. There's not much emotional drama, to be honest," he says. In the ongoing seventh season of 'GOT', Coster offered a peaceful end to Rigg's character, Lady Olenna.
