In Held Up; a romantic trip turns sour when Rachel (Nia Long) learns that Michael (Jamie Foxx) used the down payment for their future home to buy a classic car. Disgusted; she leaves him at a roadside gas station in the middle of the Nevada desert. Soon the car is stolen; thieves descend to rob the place; and the untimely arrival of the police creates a hostage situation with Michael in the middle. The circumstances want to cascade into mounting absurdity; but the ending doesn't quite provide a strong capper. Still; getting there is entertaining. Foxx is engaging; and the supporting cast--including Julie Hagerty; John Collum; Barry Corbin; and Jake Busey--create a colorful collection of locals. --Bret Fetzer
