@hitmanukDee Scroll to the top of the script and there are instructions on how to change all the output.

Quote from the top of the script::

;;;; You can change the way this script prints out by editing
;;;; %lineone, %linetwo and %linethree below.
;;;; tags must be valid and separated by a space.
;;;; valid tags are as follows: title rating votes genres
;;;; runtime director writer language country date plot
;;;; shortplot cast link trailer reviews critics
;;;; If you want to omit a line, just change it to 0
var %lineone title rating votes reviews critics genres runtime director writer language country date
var %linetwo shortplot
var %linethree cast link trailer

Edit:: I see what you are getting is the shortplot. Sometimes the short summary on imdb includes the main cast members. Your options are to use the regular plot or remove the cast from %linethree .
