The clam-shaped futuristic house featured in Woody Allen’s 1973 science fiction comedy Sleeper was sold for just under $1.53 million at a foreclosure auction according to reports.

A realty investment company outbid a loan servicing firm by one dollar to pick up the 706-square-metre house on a hill just west of Denver, Colorado newspapers reported.

According to the Denver Business Journal, local businessman Michael Dunahay bought the Sleeper house in 2006 for $3.43 million. But the lending company began foreclosure proceedings against Mr Dunahay in June, saying he had defaulted on his loan and still owed $2.77 million on the $3.13 million he borrowed to buy the house.

Mr Dunahay told the Denver Business Journal the day before the foreclosure auction that he was “working on some possibilities” for keeping the house, including outbidding the lender.

The successful bidder was named as Trans Western Real-ty.

The property was designed and built in 1963 by architect Charles Deaton.
