The worst casting in film. With so many starving actors, this is just inexcusable.

Sure, there are worse actors who never got anywhere. But these are the worst successful, popular, and over-rated actors of all time.

The absolute worst science fiction blockbusters in recent memory. Many, many, many people will disagree with this list. Why? Because most people are tasteless morons who watch reality TV and think Keanu can act. These aren't the worst movies of all time, but they have the biggest gulf between popularity and quality.
