Going to the eternal city - Rome

So I'm finally going to Italy (saving Milano for a time when the football season is in full effect!

Since Norway didn't quality for the European Championship this time either I'm gonna be cheering for Italy so I'll be in Rome from the semifinals to the finale is done, hopefully celebrating the EC victory with the italians

Anyways, I was hoping someone might have some tips on what to do, where to go except the usual recommendations from tourist sites.

Oh, and if anyone know of good places there to score old movies or independent italian movies then let me know

Any bar, club, disco, place to see the football matches etc is very welcomed

Grazie
