I was on Japanese TV. I played a Russian and I spoke 2 words in German. It was primo stuff.
Acting (& singing) in two musicals in elementary school. Traveled to other schools within our school district in southern CA.
I made my stage debut – in my PJs, no less – at age 6, with 4 pages of dialogue. That was ~60+ years ago. I’m still waiting for the phone to ring for job #2. Should be any day now.
No acting, but I did appear as the young child injured by not wearing a seat belt in a car crash. These photos were on the wall on an informational trailer that the Kansas City Police department talk around different events. So I had a tiny bit of rather weird notoriety among my peers.
My acting career started at the very top … and immediately collapsed! :eek:
Aged just a few months, I was baby Jesus in a Church Nativity play. 
My sole appearance after that was as Narrator (off stage) in a school play. 
I’ve been a background extra in a few movies. I’ve also done a lot of community theatre (including musicals, where I have to sing). And, I’ve done a lot of voice work–mainly for local commercials, though I’ve also done liners for various radio stations in the US and Canada.
I did a lot of high school and community theater, and joined a handful of improv comedy troupes over the years. I was also in a really crappy student film in college; the director scrapped his footage, remade the movie with a different cast, and I was replaced by a guy who later grew up to become cop show icon Skipp Sudduth! Decades later, here in Korea, I hooked up with a theater troupe for some sketch comedy shows, but only as a writer.
Has anybody been in a film before that topped the box office? I have convictions because of lousy former support workers messing with me, and so I wasn’t in that new Edinburgh film.
A couple years ago I played a drunk runner in a group of drunk runners all wearing dirndls for the show Chicago Justice. I am an occasionally [hasher](Hash House Harriers - Wikipedia and casting had reached out to us to ask if we wanted to be in the show and a small number of us did it along with a few other extras. Their idea of “Hashers” was that we run every day and get drunk while running so one of our guys was puking along the Chicago River and watched a woman jump in an commit suicide. That’s not exactly how it works (I mean, drink and run at the same time? That’s crazy) but it did lead to a great line by the hasher with the speaking part who said “Oh yeah, we run on Mondays, Tuesdays, Wednesdays if we’re not too hungover…” It was fun, the actors on the show were pretty cool, and it was freaking cold that night too, but it ended up being only a few minutes on the show.
When I was in high school I was in a commercial for Warp Brothers Banana Bags that showed on TV maybe just a couple times.
Elementary school play.
Quite a few internal company videos involving silly sketches. I enjoy doing them, but I can’t watch myself on screen.
I’m a drama queen.
I couldn’t be in Outlaw King or that other historical film, due to not growing a beard. But these agencies want a disclosure certificate. Mine is blootered with a lot of pointless crap.
High school: Captain Keller in The Miracle Worker; Tom Wingfield in The Glass Menagerie; Marco the Magnificent in Carnival (a musical that never got filmed, as far as I know. Only time I played the heavy).
College: Minor roles in two shows at the Yale Dramatic School. Bill Jukes in Peter and Wendy (adaptation of the first incarnation — novel — of Peter Pan, one of the lesser pirates); tuba player in Thomas Middleton’s Jacobean tragicomedy Women Beware Women, directed by George Roy Hill and reset to 1900 New Orleans. Part of the onstage jazz band that included avant-garde composer Evan Ziporyn on clarinet.
I’ve done a ton of community theater, at various theaters in my area. My “Cogsworth” in Beauty and the Beast was hailed as a triumph! 
Recently I played the lead role in a short science fiction film called “Bad Timing,” which was shown in the Short Film Festival at last year’s Balticon. Having finally been able to see the finished product, I can categorically proclaim that it was definitely a film that ran for 19 minutes.
Some community theater work. Not anything like a lot of you folks.
But, I must say it was a peak experience for me. With all the rehearsals, it was a great opportunity to bond with other people. And I am still in contact with a bunch of the co-workers. I love theatre!
I played the male lead in a high school play, including playing the violin on stage. Afterward, the drama teacher told me that I gave one of the most exciting performances she’d ever seen from a high school student.
Did a little more acting in college.
