Can You Name this Aria??

In the movie, "The Boondock Saints" there is a scene where Agent Smecka is investigating a crime scene (its his first appearance in the movie) and he is listening to an aria from a certain opera. I will give 10 points to the person who names

1.The Name of the Aria

2. What opera it is from

3.By which composer

and if you can (this will boost your chances) to tell the origional language it was written in.

(yes I already know that answer but I feel like giving points to someone)

Can You Name this Aria??amc theatre

"Si, mi chiamano Mimi" from La Boheme by Puccini.

I think that it's originally in Italian.
