The med student getting squeaky-voiced on ER last night scraped up a memory of a movie I saw 15-20 years ago, in which the climactic shoot-out scene involved helium.
The gunfight took place in a warehouse holding floats and balloons for the Macy’s Thanksgiving Parade. A bullet hit a helium tank, and pretty soon, the place was full of helium, making everyone talk like chipmunks.
Anyone remember this and know what the movie is?
