I've watched it yesterday and I really liked it. It's a weird movie full of weird but still mostly loveable characters. It has some hilarious moments (my favourite one being the scene where detective O'Grady recaps the "suicide" in the garage) but also various really touching moments, especially towards the end. My husband, whom I had to literally drag to watch the movie with me, said afterwards that it was a really good one. Guess he was suprised about that.
Oh, and Dolph? I think he was very good as this character. Oh my, that creepy make-up! I thought it was even weirder than his clothes. Especially when you think of people who actually use this kind of make-up in real life. It's not a big role but you see him various times during the movie (directly, on TV screens or on the cover of "his" book lying around) and the characters talk about his character. So he stays in mind. And he's also part of a great ensemble. Dolph's character is - like almost all characters in this movie - a caricature with some funny and some not so funny moments. That's what I like about it. He gets normal moments, neither the "hero mode" nor "clown mode". And he is convincing.
I was quite surprised about Johnny Knoxville. Still didn't manage to watch Jackass and somehow I didn't notice him in Walking Tall back when I watched that one. So I had this image about him in my head that was wiped away with the first scene. He has something very friendly about him that I hadn't expected. Also he was much taller than the rest of the cast. Checking IMDB it says that he's 1,85m (6'1) which is tall but not gigantic. So the rest of the cast must have consisted of dwarves. ;-P Amanda Plummer, who is 14 years older than Johnny, played his mother. That was kind of weird because although she was dressed like an old woman her face looked younger than Johnny's. Guess it might be different life styles.
It was a big cast and every single one, famous or not, was really, really good. Didn't say much about Matt Lucas, Billy Christal, James Caan or Peter Stormare. Of course they were brilliant. But so were all the others. It's an odd gem. Made me laugh and cry. In all this oddity I related to these weirdos who just tried to find a happy or at least decent life somewhere in this unlikely place.
