Kristen and Jesse no talent, miscast
Kristen Stewart simply didn't have the talent or range to deliver this role. When the script called for anything marginally demanding she fell flat: She couldn't cut it when she had to tell Jesse that she was marrying Steve, or in the nightclub when she was called upon to act like a shallow, gossipy Hollywood wife. The depth, maturity, commitment, drive and passion needed to make this role work simply weren't there.
Jesse Eisenberg: He's been a competent actor every other time I've seen him, but just like Stewart, although slightly better, when he was called upon to stretch he didn't have it. I can't help but compare him, vastly unfavorably, to Kenneth Branagh, who also played "Woody Allen" in Celebrity. And when he poured on the fake, smarmy charm I wanted to puke! Right after fighting an overwhelming impulse to jump into the screen and punch him in the face. He was woefully miscast and out of his depth when he was wearing the white tux in the nightclub and walking around with that unctuous smile on his face trying to charm everyone. Sorry, but Humphrey Bogart in Casablanca he is not!
We got a job.
What kind?
