'Kill Bill' Star Michael Madsen Domestic Violence Case Declined

8/27 -- 11:08 AM PT -- The Los Angeles District Attorney tells TMZ the Michael Madsen case has been declined for filing by our office due to insufficient evidence.

Michael's rep tells TMZ ... "We are thrilled that Michael Madsen is able to put this behind him and look forward to our continued collaboration with more great things coming from this veteran and respected actor."

Michael Madsen spent part of his weekend in jail ... because cops arrested him after he allegedly pushed his wife.

Law enforcement tells TMZ ... the 'Kill Bill' actor was arrested shortly after midnight Saturday on a misdemeanor domestic violence charge.

Police allege Madsen pushed his wife and then locked her out of their Los Angeles-area home after a dispute ... though it's unclear what may have set him off here.

We're told cops were called, and by the time Los Angeles County Sheriff's deputies arrived at Madsen's home, his wife was safe with a security team.

Police say the deputies spoke with Madsen and his wife, then arrested him and hauled him off to jail.

Meanwhile, we're told Madsen's wife refused medical attention.

The veteran actor of other Quentin Tarantino flicks -- like "Reservoir Dogs," "The Hateful Eight" and "Once Upon a Time... in Hollywood" -- ultimately posted a $20,000 bond ... and was released from custody.

TMZ reached out to Madsen's team, who tell us ... "It was a disagreement between Michael and his wife, which we hope resolves positively for them both."
