Madsen is planning to rejoin the trip in Boston
Film star Michael Madsen has left the European leg of the Gumball 3000 Rally after police stopped his driver for speeding, event organisers said.
A Gumball spokeswoman said the Reservoir Dogs star had decided to head back to the US to rejoin the rally when it arrives there later this week.
Madsen, who had been travelling through Belgium in an Aston Martin, was one of several celebrities taking part.
The Wire's Idris Elba and US singer Eve were among the other drivers.
The Gumball 3000 involves more than 100 cars driving 3,000 miles between London and New York, taking in Amsterdam, Copenhagen, Stockholm, Boston, Quebec City, and Toronto on the way.
The cars will be flown from Europe to Boston. The rally will finish in New York's Times Square on Friday.
It costs £30,000 for two people in one car to enter. Those taking part are expected to respect the rules of the road.
The event was hit by controversy three years ago after a crash which left two pensioners dead.
Cheshire businessman Nicholas Morley was given a two-year suspended sentence after being found guilty of "endangering traffic, leading to death".
