Former Luthor Corp employee Earl Jenkins, and who also worked at the Kent farm, has an unknown disease that violently shakes all his body. He arrives at the Kent farm during a party Clark throws while his parents are out of town and claims that the disease developed following an explosion at his former workplace: Level 3 of Luthor's Smallville plant which was experimenting with meteor-rock laced fertilizer. Trouble is, there is no Level 3! Determined to prove his case, Earl breaks into the plant and takes a class touring the plant hostage. Lex arrives with the police and trades himself for the hostages, while Clark stays behind to try to help Lex and find out more about 'Level 3' which Lex claims to know nothing about. But Lionel apparently knows about the mysterious secret underground level when he arrives with his personal goon army determined to keep the secret experiment under wraps... at the expense of anyone, even his own son Lex.

Did You Know?


The fourth episode to be filmed. "Jitters" was originally slated to run as the second episode. However, because of constant changes and retooling to the script it kept getting put back in the schedule. This explains why the episode had three directors - Michael W. Watkins, Greg Beeman and Philip Sgriccia. See more »

Decent Filler Episode...
9 August 2010 | by (Canada) – See all my reviews

Not a favourite episode of mine, as there is no real villain. Tony Todd guest stars as Earl who has an unknown mineral in his skin and causes his body to try and push it out in a jitters like way. His involuntary shaking is extremely strong and because it's kryptonite in his skin, he weaken's Clark and disables his abilities.

He continuously looks for level three at the LuthorCorp plant, but according to everyone, it doesn't exist. The effect of the jitters looks like a visual and special effect at the same time. It's not very exciting to watch and after the third or fourth time happening in the episode it can get quite tedious to watch.

Aside from that, the character of Earl and the plot of the episode is kinda dull. I don't actually like this episode very much. It seems more like a filler episode just to continue showing Clark's ability to be a hero and show off his powers.

No real character development happens, chemistry between the characters is not really shown, and the only real action is at the end of the movie. However, the action that is shown isn't a fight between Earl and Clark, it's actually just an accident that causes Clark to struggle to save Earl and Lex.

Lex is basically the only character to gain development from this episode aside from Clark. He tries to be a hero and save all the high school students from Earl's jitters or whatever he's planning to do to get to level three. Not that it's a bad thing, but this episode doesn't contain many things enough to enjoy it as the previous episodes have. I merely watch this episode for the sole purpose of it being in chronological order to get through the season.
