I am on a Rocky Horror Cast in Northern VA… One thing you do need to know is that rice, water guns, and candles are against the rules in many theaters. Check the theater rules before bringing such items. Many theaters have a website, if not, find the cast’s website. You can use

And search your city or state to see if the cast has a website.

I’m sure you’d rather do research then get kicked out of a theater without a refund!

Rice: At the beginning of the film is the wedding of Ralph Hapschatt and Betty Munroe. As the newlyweds exit the church, you should throw the rice along with the on-screen wedding guests.

Newspapers: When Brad and Janet are caught in the storm, Janet covers her head with a newspaper The “Plain Dealer”. At this point, you should likewise cover your head.

Water pistols: These are used by members of the audience to simulate the rainstorm that Brad and Janet are caught in. (Now do you see why you should use the newspapers?)

Candles, flashlights: During the “There’s a light” verse of “Over at the Frankenstein Place, “you should light up the theater with candles, flashlights, lighters, etc. (Be careful to respect the theater’s policy about open flames – remember you are wearing newspapers on your head!)

Rubber gloves: During and after the creation speech, Frank snaps his rubber gloves three times. Later, Magenta pulls these gloves off his hands. You should snap your gloves in sync each time to create a fantastic sound effect.

Noisemakers: At the end of the creation speech, the Transylvanians respond with applause and noisemakers. You should do the same.

Confetti: At the end of the “Charles Atlas Song” reprise, the Transylvanians throw confetti as Rocky and Frank head toward the bedroom. You should do the same

Toilet paper: When Dr. Scott enters the lab, Brad cries out “Great Scott!” At this point, you should hurl rolls of toilet paper into the air (preferably Scotts).

Toast: When Frank proposes a toast at dinner, members of the audience throw toast into the air (preferably unbuttered… things could get sticky).

Party hat: At the dinner table, when Frank puts on a party hat, you should do the same.

Bell: During the song “Planet Schmanet Janet,” ring the bell when Frank sings “Did you hear a bell ring?”

Cards: During the song “I’m Going Home,” Frank sings “Cards for sorrow, cards for pain”. At this point you should shower the theater with cards.

Hot dogs and prunes: It has happened on occasion, that fans will throw hot dogs and prunes at their appropriate mention in the film. This should not be encouraged because it attracts rodents and leaves stains on the screen.

Well I have never gone myslef, but i have seen the movie many times. I know sometimes people will bring ponchos, b/c other people throw stuff, but other than that at the beginning of the movie when the couple get married the audience throws rice at them, and stuff like that throughout. There is also a bunch of lines the audience says.

You can dress up like any of the characters or just dress like a drag queen in general.
Sorry I dont have more info, but you might be able to just look it up on google or something! Good luck! Watch the movie and you’ll be able to catch on!

You need a newspaper for when they are in the rain, and rice to throw during the wedding scene. I can’t remember what else lol

Bring toast and when they say “a toast!” in the movie, you throw the toast. That all I remember, haven’t seen for like, 20 years..
Oh, and raw rice for when Janet get married.

Dress up as Frank n Furter, Magenta,Rocky, Brad,Janet or Riff Raff.
