Act: The Modern Actor’s Handbook

3.5 and rounding up.
As someone who studied a number of acting methods in my BFA program, I found this to be a nice combination of many that I personally found very helpful.

If you just breaking into the industry, this a very approachable guide to navigating scripts, productions, and auditions.

I am not a huge fan of audiobooks for texts like this because I like to annotate, so between that and the audio quality of this (the audio sounded very compressed and low volume), I would not recommend the audio version unless it's the only way you'll be able to read it.

***Thank you to ECW Press Audio for providing me with a copy of the audiobook for free via NetGalley for an unbiased review.
