Man living on his own

Movies

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!

Thanks

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