Multiculturalism seldom runs hotter than it does in the skinternational production Russian Dolls (2005). A group of college friends reunites in Barcelona five years after spending a summer together. They've been scattered all over the world in the ensuing period, but once they come together again, their chemistry is recharged. The men live it up while the ladies take it off. Russian Dolls, like the toy from which it gets its title, works best when there are females revealing what they've got hidden underneath. And, on that front, this movie works plenty.
