Tough-guy actor Michael Madsen ('Kill Bill,' 'Reservoir Dogs') is a wanted man.

Madsen, 53, allegedly owes an estimated $570,000 in child and spousal support, according to a new report from TMZ.

A warrant has now been issued for his arrest, as legal documents show he failed to appear for a hearing last week in his ongoing child/spousal support case.

When Madsen, who is the brother of Oscar nominee Virginia Madsen, was a no-show in court, the judge issued the warrant. Police are looking for Madsen now; bail has reportedly already been set at $26,000.
