“Cash Out” (**1/2 out of four) was an efficiently done B-thriller about a professional thief (John Travolta) who decides to rob one last bank with his brother (Lukas Haas) but plans go awry and they are trapped inside while he has to confer with the hostage negotiator (Kristin Davis) who is his former lover. Routine story with obvious influences from “Dog Day Afternoon” and “Inside Man” but is enlivened by strong cast and some snappy dialogue that elevates it above the norm. A sequel is already wrapped and coming soon.
