Who's the Dumb Blonde?

Kim Basinger stars with Val Kilmer in this clever caper about a reformed master cat burglar who's blackmailed into doing one last job with an amateur partner-in-crime.
After six long years in prison for a failed bank robbery, legendary criminal Karen McCoy (Basinger) wants nothing mare than to turn her life around. But her hopes are soon shattered: No one will hire her, she's stuck with a sleazy parole officer, and her ex-husband has told their son that she's dead. To make matters worse, crime lord Jack Schmidt (Terence Stamp) is forcing her to pull off a seemingly impossible $18 million bank job with the full knowledge that once she hands over the money, she's history.
Now, with the help of an eager but inept would-be thief (Kilmer), Karen must use all her talent, ingenuity and technical wizardry to execute a seamless bank heist, outwit her enemies. . .and stay alive. It's Basinger at her most beautiful, beguiling --and dangerous -- in this stunning suspenseful adventure with an accent on excitement!

This movie is lighthearted and a lot of fun. While not usually thought of as one of Kilmer's comedies, it can be very funny at times. After all it's not often you get to see Kilmer play the dumb blonde role, as one reviewer described it.
Kilmer and Stamp also appeared together in Red Planet.
