Little Shop is a great show. The production I was in, was not so great. I'm just being honest as possible... it really wasn't. We had direction issues, and a lot of the show was in a sense put on by the actors themselves. The show was an average success. People enjoyed it, and some people did not enjoy it. I'd love to do it again, but correctly next time.
I don't recall any bloopers in this production, just angry actors (which can be funnier than bloopers sometimes).
Advice for others:
Give the Audrey II a lot of physicality and personality. It sounds obvious, but a lot of people just do the movement, and don't give it any form of personality. When using the puppets, make sure you rehearse A LOT with the singer for the plant. I suggest bringing a video tape to rehearsal and recording your movement so you can review it at home to make your performance better.
