The Big Bang Theory's ending was more chaotic than initially perceived. Here's what every main cast member has to say about its sudden cancelation.

I have not read the article but each one of them should be forever grateful that they were chosen to be on this show and how this show has lasted for 12 years, making all the actors very wealthy. Besides Johnny Galecki and Blossom, none of the others were well known at all. I think a lot of casting to be on a successful series is being at the right places at the right time.
