Just put a whole bunch of bad actor/actrsses in it.

All actors/actresses who did something related to Superman have gone down the shitter.

Christopher Reeve broke his back and just recently died.

Dean Cain, supposedly one of Hollywood's promising stars is already washed out.

The lady who plays Clark Kent's mother in "Smallville" disappeared for quite some time before the show preimered. If you are wondering, I believe she actually played Lana Lang in a Superman movie or two.

Teri Hatcher also had a long hiatus and might possibly break the "Superman Curse" with "Desparate Housewives."

I know there are more, but cannot think of any off of my head.
