[Plugin: IMDb link transformer] Remove lines below actors, writers, etc.

Hey there,
first of all, thanks for the great plugin, really helps alot by adding more content to my posts.
I was wondering, if there is a possibility to remove the “lines” below the actors or writers, as you can see in this example:

I was searching the .css and the .php for any signs of code that’s responsible for that, but couldn’t find one…

Thanks in advance and keep up the good work!
