A low-key Murphy, whose “Beverly Hills Cop: Axel F” sequel was released straight-to-streaming by Netflix last year, is the responsible adult here. Davidson, the Jerry Lewis to his Dean Martin, portrays a sentimentalized version of the idiots he sometimes plays.

Keke Palmer and Eva Longoria also star in the latest feature from director Tim Story ('The Blackening'), about a pair of armored car guards who get ensnared in a deadly pursuit.
