I'm not quite sure what you're trying to do in the Attore view. You get an
actor, but then iterate through all actors in all films that that actor is
in.
If you just want to show the details for a single actor, why iterate at
all? Just get the actor as you're doing with `get_attore_id` (which by the
way is a strange name, because `get_` implies it's a function, which it
isn't, and you're not getting the ID, you're getting the Attore object: it
should probaby just be called `attore`.), and don't bother with the film.
And remove the for loops from the template, and just output the details of
the single actor.
