2018 Acts Of Violence (2018)

Generic action flick where some brothers rescue their sister from baddies by doing lots of shooting people.
Bruce Willis is in it for a bit.
I reckon he's got some kinda stupendously expensive hobby, like firing solid gold cannon balls into lakes that he doesn't bother to retrieve.
Well, he must've earned fifty lifetimes worth of money in the '90s, so he's gotta have a reason for appearing in old cockwash like this?
