Before watching the movie:
I’m not quite sure what this is. The synopsis I’ve seen about a rock star getting involved in a counter-operation on a Nazi attack on submarines is simply confusing, and I have a hard time picturing Val Kilmer and not someone like Brendan Fraser, but its cult reputation that I’ve very recently stumbled upon is that it’s a Zucker/Abrahams/Zucker comedy of the same caliber as Airplane!. That’s a tall order to fill, since Scary Movie 4 tried and failed to live up to it, and even The Naked Gun franchise eventually let me down (the first one is good, and I look forward to the short-lived TV show it was based on).
Also the presence of cows in boots on all the posters baffles me, but that’s probably intentional.
