I haven’t read anything by Elmore Leonard, so I can’t comment on the book-to-movie aspect.

Seemed like it might’ve made an amusing book, but it didn’t really (IMO) translate well to the big screen.

I liked the idea of comparing mobsters to hollywood insiders (but that couldn’t sustain a whole film) and there were some amusing moments (like Chili’s minivan), but it just didn’t do anything for me.

The glib chatter just didn’t interest me, maybe it tried too hard. The loose plot of movie w/in a movie was too weak and tried to do too little with too much. The actors seemed like they were phoning it in.
Devito & Hackman & the guy that played Leo were pretty funny, but nothing special. Russo was just there as the one-dimensional “girl”. Travolta’s a brainwashed cultist (Scientology) who had basically one line “look at me”…. so I just tried to pretend he’s not in the film. Dennis Farina, though I like him on Law & Order was cringe-ingly awful and hammed up.
I just kept thinking, ok, stereotype of mob guy, stereotype of hollywood, stereotype…. where’s the humor?

I’ve seen a lot worse so I won’t say avoid….
Watch if you’re really bored… but don’t expect much.

I can not understand the hype around this film.
