What does levelling actresses up do?

Question

Pretty self explanitory

Answer 1

they can take more classes, so they definitely make more money at the tent, and are able to become stars (all 3 grades of it).

I do not think however, that it affects the grade of the movies, if thats what u really wanted to know.

 

So simply put,  dont hesitate letting an actress go and get a better one, the lvl isnt important at all

Answer 2

It does not affect the rating, but the income with leveled actresses (star(let)) is better;-)
