It's also a nod to cinema's greatest teen-nerd iconoclastic hero. Smart rich kid Charlie Bartlett (Anton Yelchin) has trouble fitting into his new high school. But he sticks to his strengths -- brains, empathy and easy access to prescription drugs -- and soon finds himself popular and sought-after, first as the school's resident therapist, and later as its rebel-with-a-cause, butting heads with authority. Former bad boy Robert Downey Jr. portrays the frustrated principal, and it's a nice bit of casting that lets Downey's just-middle-aged character express grudging admiration for young Bartlett's brio. Charlie openly tips its hat to Hal Ashby's quirky 1971 classic Harold and Maude: Charlie's wealthy, slightly out-of-focus mom (Hope Davis) recalls Harold's momma, and Poll's choice to have Charlie perform Harold's theme song, "If You Want to Sing Out, Sing Out," nails it.
