Neville Longbottom role in the Harry Potter movies hasn’t been an important one.
In the last movie though, we started seeing the first hints that he is more than a joke especially when he stood up to Voldemort’s invading lackeys on the train.
In the next movie Harry Potter and the Deathly Hallows Part 2 he’ll get a bigger role, this is why the poster today.
Longbottom is holding, as you might have noticed, Gryffindor in his hand. Yes the same sword Ron and Harry retrieved from a lake in the last movie, for their fight against Voldemort.
