Oh, yes. I forgot to answer those questions. Sorry. It’s been a distracting morning.
You sit in a regular theater seat, as if you’re watching a play.
Shows are scripted, but (as they discussed in the KS livestreams) the scripts evolve. If they find a riff isn’t landing with the audience, they’ll replace it. If people are laughing so much at one riff that you can’t hear the next, they’ll take the next out. If the cast gets bored of the current riffs as the tour goes on, they’ll mix it up and try some new ones here and there.
Audience interaction in the live show I saw was pretty much limited to asking us to do a particular call and response and to blasting confetti and stuff at the front rows.
Available concessions depend on the theater you’re going to. The Alamo Drafthouse Theater has waitstaff who will bring you drinks, snacks, and burgers, and every seat has either a ledge or a counter. It’s just the way the Alamo Drafthouse chain works. The theater in NYC was more like a regular movie theater, just with a stage built in front of the screen (so they could use it for stage shows, movies, media presentations, etc). So you could get the usual movie snacks from the lobby, but that was it. Look up the venue where you’re going and see what they offer.
The show itself consists of the cast coming on stage to introduce themselves and the show and prompt the audience for anything like the call and response bit, then a host segment where they talk with the Mads, then watch part of the movie, and so on. The bots are there with puppeteers behind the set pieces.
The details will depend on the show. I think they try to mix it up a little from one tour to the next. You might not know what movie you’re watching until the show starts. (Sometimes they tell you, sometimes they keep it a secret.) There’s merch available, some of it general, some of it specific to the tour. T-shirts, of course. But sometimes more unique items. Whatever’s relevant that they think people might want.
I’m not sure what the meet & greet entails, and if it’s before or after the show. Cinematic Titanic regularly had the cast manning the merch tables at the end of the show. Which meant the line was long and slow-moving, but if you stuck with it you could say hi, get your stuff autographed, and maybe get a picture. (They were really cool about it, hanging around for a long time after the show to make sure that everyone with the patience to stand in line got full service.) MST3K Live didn’t really do that anymore, so meet & greet will be a more special opportunity.
