This romantic comedy could have been a smarter, sexy take on something like Bridget Jones's Diary, but another smutty, if watchable Anna Faris (Take Me Home Tonight) movie is too underwhelming.
A scattershot What's Your Number?, costarring Chris Evans (Captain America), does aim to ingratiate willing audiences with Faris's comedic talents. Her lovelorn Ally Darling contemplating a life of spinsterhood after waking up and breaking up with her beau (Zachary Quinto). After Ally is fired she peruses a magazine where an article relates being single for those having nearly the same amount of sexual partners as her.
The screenplay from Karyn Bosnak's book isn't very high-minded on the distaff side as Ally's sister Daisy (Boston native Ari Graynor of Date Night) is about to get married and the younger sibling has to find out which of her exes is the one she shouldn't have let get away.
Evans has a little of that "friends with benefits" charm as the neighborly buff lothario who is the recidivous guy to fulfill Ally's goal. Director Mark Mylod, for a while, makes this search (with trips to the gynecologist, politics and physical and unbelievable transformations) occasionally amusing, but the proceedings don't have a consistently witty payoff like the lewd, if skittish Bridesmaids.
There isn't much devoted to the characters as Faris gets her prat-falling moments and baring more than she probably was necessary. The actress who is married to one of her co-stars here (Chris Pratt of the involving Moneyball) is game in accentuating a role that requires good timing for this kind of desperate young woman.
Blythe Danner (Little Fockers) has another stock role as Ali's mom, and with some occasional flash backing, there are notable appearances or extended cameos by the likes of Martin Freeman and SNL's Andy Samberg.
Overall, this adaptation of Bosnak is too unambitious and telegraphed, exposed for its shallowness and even flabbier than Faris's funny Turn in The House Bunny. Broad and obvious to reach a junk-food fueled audience, What's Your Number? is too light and shallow to turn a frog of ditzy, raunchy entertainment into a prince.
