fergie38, I don't know which movie you are referring to. But here are links to two YouTube videos of The Dickie Cups singing "Iko Iko:

Dixie Cups - Iko, Iko.

[The poster's summary just says "show". I wrote a comment asking for information about which television show and what year it was filmed, The women are shown performing on a stage, and not shown banging on a glass bottle. However, I've read that the song was recorded as the women were "fooling around" in between takes at a recording studio. I doubt that there is actual footage of the first time they sang this song that they learned in New Orleans.
