Man living on his own

I’m trying to remember a film where a man lives on his own and constantly gets tormented by teenagers. I thought the man was played by Michael Caine but going through his filmography it appears he doesn’t.

Can anyone help!


I’m an idiot. Found it! Harry Brown

“Gran Torino” (2008) with Clint Eastwood?
EDIT: OK, I see you have found it.
