The Princess Diaries (2001) review

Gawky fifteen-year-old Mia Thermopolis (Anne Hathaway), who lives with her artist mother Helen (Caroline Goodall) in a renovated fire station, is invited for tea with her grandmother Clarisse (Julie Andrews) who informs Mia that she's the heir to the (fictitious) country of Genovia, which comes as a shock to the teenager since she only has one friend, outspoken Lilly (Heather Matarazzo), and is mocked by her classmates on a daily basis.  The movie's core "dilemma," about whether or not Mia will accept the role of Princess, isn't some great mystery (take a peek at the poster), so the rest of it consists of consistently placing her in situations where she stumbles and bumbles her way around, which quickly becomes obnoxious: she fails at every sport, regularly falls down, is unable to deliver a speech without becoming nauseous, ruins a dinner party, damages her refurbished Ford Mustang, and so on.  The supporting cast is decent - the presence of Andrews classes the joint up, Héctor Elizondo's head-of-security acts as a surrogate father - and who knew all it took for a high school "dork" to look "regal" is to lose the glasses (and Doc Martens), do a little plucking and straighten out the frizzy hair.  Perhaps a Bioré pore strip could help as well.
