This is not a love story, declares the opening narration of (500) Days Of Summer.
And watch out for a terrific Harrison Ford reference that brings a smile a mile wide.
Central to this is Gordon-Levitt.
If Deschanel feels a little sidelined and underwhelming by comparison, then its not all her fault.
Elsewhere though, the film has a supporting cast that adds a winning mix of laughs and heart.
While dependable supporting player Clark Gregg has a handful of nicely played comedy moments as Toms boss.
(500) Days of Summer is released in the UK on 2nd September.
