Steve Carell’s best film performance to date can be found in the fitfully engaging Dan In Real Life, where his long-suffering persona suits a character who lets his long-dormant hopes rise for a moment, only to be shot down again. Carell plays Dan Burns, a newspaper columnist who writes about family issues and relationships. As a widower with three growing girls to raise, however, the difference between Dan’s printed wisdom and his struggles with fatherhood and loneliness is often vast.
