The day after the attacks on the Twin Towers, he turned up at his old fire station ready for work. He spent the next week doing 12-hour shifts and helping his former colleagues search for the bodies of the missing. When people tried to get photos or interview him - he outright refused.
Buscemi had worked as a New York City Fire Department (FDNY) firefighter with Engine 55 in Little Italy. He stayed in touch with some of his old fire company colleagues, even when he went on to be a Hollywood superstar. He understood how many firefighters were missing along with the rest of the innocent people who'd been affected by the terrorist attacks, and just wanted to help out.
"It was great to connect with the firehouse I used to work with and with some of the guys I worked alongside. And it was enormously helpful for me because while I was working, I didn't really think about it as much, feel it as much.
"It wasn't until I stopped that I really felt the full impact of what had happened. It would have been much harder for me to get through it if I hadn't been able to do that."
'A Good Job' also has a message to current firefighters - don't be afraid to ask for help after any trauma they may have suffered.
