Cadillac Man is a 1990 American black comedy film directed by Roger Donaldson, starring Robin Williams and Tim Robbins.

The plot of the film centers on car salesman Joey O'Brien (Williams), whose life is consumed by turmoil, which all comes to a head when his dealership is taken hostage by Larry (Robbins), a love-crazed motorcyclist.

[2][3] Queens car salesman Joey O'Brien must deal with the ever-increasing pressures in his life: he has an ex-wife demanding alimony, a daughter who is missing, a married mistress and a single mistress who are both desperately in love with him, and a two-day deadline to either sell twelve cars or lose his job.

The crisis resolves all of Joey's problems: his mistresses learn of each other and dump him, his daughter returns, his job is secure, the Mafia don (whose son was among the hostages) forgives his debt, and he begins to reconcile with his ex-wife.
