Some films are made so bad that they are funny. "Allan Quatermain And the Lost City Of Gold" falls under that category; this is far beyond the most awful film I have in my collection. The script I'm sure disappeared on the first day of shooting, the acting is even worse and the special effects look if it had a budget of a couple of pounds. This is all elements which becomes the force of the film. You're not laughing because it's fun, but because it's bad. Maybe that's why I can still be entertained by it.
"Allan Quatermain And the Lost City Of Gold" is the adventure genre's "Plan 9 From Outer Space" (though the special effects are slightly better), and I can still enjoy watching this delightly dreadful disaster of an adventure film.
