Hollywood star Keanu Reeves made his professional racing car debut on Saturday, but spun off the track at the famed Indianapolis Motor Speedway.

The Matrix star Reeves spun into the grass without a crash on the exit of turn nine, a little more than halfway through the 45-minute race.

He re-entered and continued driving, signalling he was uninjured.

Reeves, who qualified 31st out of the 35 cars, ran as high as 21st and successfully avoided a first-lap crash at turn 14. He finished 25th.
