a sound of a thunder

Frankly, yes. We don't want anyone going who'll panic at the first shot.
Trying to scare me!
Why?
Step on a mouse and you crush the pyramids. Step on a mouse and you leave a print, like a Grand Canyon, for eternity.
AAAAAAAAAAAAAA
Eckel arriving and preparing to go into the Time Machine with the rest of the team
Eckle and his team travelling to the past
I'm innocent, I didn't do anything wrong!
Take it easy, all he did was kick up dome dirt
Eckels, never come back.
They arrive and when Eckle sees the T-rex he chickens out and says he can't kill it
You joking? You know very well. Deutscher, of course! Who else? Not that fool weakling Keith. We got an iron man now, a man with guts!
Did Keith win the election?
The men shoot at the T-rex, and Eckel began running back to the machine, but he steps outside the path.
When Eckles gets back he accidentally stepped on a butterfly while running to the machine and Travis noticed and he gets mad.
Eckle noticed there was a difference when they returned home and so did Travis. So Travis kills Eckle after he finds out Eckle changed the future.
