I have to place the movie Anaconda is this illustrious list. I'm not sure if it was meant to be funny but we sat there and laughed at some of the scenes and bad acting.
The one scene I remember vividly is where they showed a scene of the boat pulling away from the shore into the river. Rather than film the boat leaving the shore the producers decided just to take the scene of the boat arriving at the shore and play it in reverse. Someone forgot that there was a waterfall in the background, so as the boat was 'pulling away' from the shore the waterfall was going up.
