I think it's very rare, as an actor, that you get to a script, or an idea of a script, and you go, "Oh, I just have to do that!" It fell into place very quickly.
My easiest judgment for a script is 'do I want to keep reading it?'
You can tell if you're going to be into a script within the first five or ten pages - if I'm not completely engaged by page 20, I just have to give up on it.
You'll read a script, and it'll grab me, or it won't.
There are definitely scripts I start reading, where it doesn't interest me. Maybe it'll be a good movie, but the character doesn't intrigue me.
Normally, when I read a script, I read 30 pages, and then go have a cup of tea and come back. And then, I read 20 pages and go make a phone call, and then go back to it.
I opened the script to the 'The Wall,' and 15 minutes later I was done with it, and I loved the movie and wanted to be part of it.
I ensure that I read the entire script of each project that comes my way. In fact, it is the script alone that evokes my interest in any film.
If the script grabs me and appeals to me, I'm really very keen to work on it.
If I put the script down more than once, there's a good chance that I probably don't want to play the part.
You read a lot of pilots during pilot season, and not all of them really grab you.
