I've mentioned in past threads, but I'm in the same boat as Katsuro. The most prominent thing I've done so far was Day One (though I still tend to call it Renee after its working title), but I've had larger parts in a variety of stuff. I did 16 or 17 days as background on Game On!, which included some scenes directly interacting with the main actors; at least one episode included me as part of one of the gags, just minus any lines. Since the show is set in a static company, it made sense for them to bring back the "other employees" as often as possible for continuity's sake; I was there so much that I had my own labeled makeup bag and a character name.
That's pretty awesome. I've only ever done GoT, I think because I have a very...ummm...specific look lol. Also not a lot of major stuff is filmed in NI, although that might change thanks to some high profile stuff like GoT and Your Highness. I did get offered the Dracular movie but I was in Australia at the time so couldn't do it
. I've done it GoT enough that most of the costume and hair&makeup people know my name but I haven't risen to the level of having my own sepcial set of stuff and a character name, and probably won't either as that doesn't really happen to our extras.
I've also not really had scenes interacting with the main actors, despite being in the same shot as them sometimes - unless ruining a shot by accidentally running into and tripping over Rose Leslie counts lol. Also I did have a scene in Season 3 where I get shoved out of the way by Anton Lesser, but the shot cuts to a totally different angle before that happens so you don't see it in the epiosde.
