Michael Madsen has been charged with two counts of driving under the influence (DUI).

The Reservoir Dogs actor was arrested in Malibu in September after being stopped for driving erratically and subsequently blowing a .20 on a breathalyzer test - more than twice the legal limit - and last Wednesday, the Los Angeles City Attorney filed two misdemeanor counts against him, one for driving under the influence of alcohol or drugs, and another for driving with a BAC of .08 or higher, gossip website TMZ reports.

The case is scheduled to go before the court later this month, but Michael's attorney - who previously declared the breathalyzer test "flawed" - said, "We intend to vigorously defend the charges."

If convicted, the 55-year-old actor could face up to two years in jail but as he has no previous DUI convictions, it is unlikely he would serve any time in prison.
