I had avoided the 2007 movie Lucky You (starring Drew Barrymore and Eric Bana) because I had the impression that it wasn't really about Las Vegas, but focused more on the love story between the main characters. I was wrong.
While the love story is prominent, the movie is heavily based on Las Vegas, poker and gambling. The dialog is really strange - it's like the writers had a poker glossary and tried to use each and every term before the end credits. Some of the most ridiculous "people don't talk like this" stuff I have ever seen in a movie.
Lucky You isn't good - but I strangely would encourage any Las Vegas or gambling fan to watch it just to see how bad it is. It falls into the "so bad it's good category" in my opinion. With so much gambling jargon being thrown around it's almost like watching a parody of a poker movie at times.
The cast isn't terrible with Robert Duvall, Robert Downey Jr. and Michael Shannon having supporting roles, which makes the insanity of the robotic dialog even more head scratching.
As far as Las Vegas scenery, they didn't do much in the way of creative hotel placement that you sometimes see in Vegas movies. Most of the poker action takes place at Bellagio and Binion's (or sets made to look like those places, although the film was shot on location in Las Vegas).
I was expecting to see a standard run of the mill rom-com that I watched just because of Las Vegas, but what I got was a crazy movie that I honestly want to watch again to make fun of the dialog and improbable poker scenarios that play out.
