Rent Stand Off (2011)

In an attempt to protect his family and pay off his gambling debts to a local gangster, Jimbo robs the local fish market unaware that it's owned by the gangster. On the run, he hides out in an antique shop where he takes hostage a group of people, including Maguire (Brendan Fraser) who may (or may not) be his father. Surrounded by the police, the SAS and the gangsters crew, Jimbo must use his wits (and some antique guns) to try and stay alive.
