"The Castle Keep" - I won't even waste anyone's time with the IMDb link.
The storyline about saving a castle and it's artwork from "Nazi soldiers" *may have* been a sound script, but what a sad end result plagued by poor dialogue, terrible acting, ridiculous costuming (and the actors looked like they just fallen out of a 70's sitcom) and LAME special effects.
After watching this, I *almost* wanted to watch Pearl Harbor in a desperate attempt to get the terrible memory out of my head...
