Speaking to INSIDER at Con of Thrones in Dallas, Texas, Joe Dempsie said that he has finished filming the eighth season of "Game of Thrones."

Dempsie, who plays Gendry on the series, said that he shot his final scene last week.

The actor said it felt bittersweet to finish his time on the series.

Although fans will have to wait until 2019 for the eighth and final season of "Game of Thrones," the series is beginning to wrap up on set and members of the cast are beginning to finish up their time in Westeros.

Among those who have completed their time on the show is Joe Dempsie, who plays Gendry.

"I finished last week for good," Dempsie told INSIDER at Con of Thrones in Dallas, Texas. "It's a very strange feeling actually. There have been people who have been finished periodically over the past month or so, and even watching other people finish was quite emotional at times."

Dempsie said he was on set with other actors who were also filming their final scenes the same day.

"I thought I was all right, I thought I was going to be fine," Dempsie said. "And then I happened to be finishing on the same day as a few other actors as well. When they did my little bit I was fine, but it was when they got to the other people that I lost it a little bit. I'm fine until I see someone else trying not to cry, at which point I'm done."

For Dempsie, filming the series' end felt bittersweet after having so many cast members come together who previously hadn't been able to work together in the same place as often.

"It made us all reflect on the years gone by. This season was such good fun because everyone's converging on Westeros now, so you get to see a lot more people," Dempsie said. "Because in years gone by you might be ships in the night, filming in some other part of the world, so you wouldn't really get to see people. Whereas we got to hang out a lot together this year."

The "Game of Thrones" cast has deeply bonded on set over the last nine years, forging friendships that are sure to continue one. Dempsie said the final season has been like the last year of school.

"It just brought home the fact that we're not going to be able to count on these six months every year to see each other," Dempsie said. "We're going to have to actually make an effort. It's like leaving school, exactly the same thing, where on your last day you know there are people you'll see again, because they're your mates, but you just know you're going to have to make an effort to do so. And then there are those people you think, 'I might not actually see them.'"

Even though we haven't seen Gendry on the show since his marathon run to Eastwatch in "Beyond the Wall," he should be back for the eighth season. If you're impatient to learn the fates of the rest your favorite characters, read our list of 21 key predictions we have for season eight in the meantime.
