Cars effortlessly cruised to the top of the US box office over the weekend, displacing The Break-Up from the top spot.

Despite taking a healthy $62.8m, this does not stand it in good stead in comparison to the previous two Pixar offerings, with both The Incredibles and Finding Nemo grossing in excess of $70m in their opening weekends.

Also debuting over the weekend were horror remake The Omen and A Prairie Home Companion.
