Don't panic! It's top

The Hitchhiker's Guide To The Galaxy has beaten Hollywood heavyweights to top the US box office.

The movie version of Douglas Adams's cult novel, starring Martin Freeman from The Office, raked in $21.7 million (£12million) last week.

It beat action blockbuster XXX: State Of The Union, which made only $13.7 million despite costing $87million to make.

The Hitchhiker's Guide opened in Britain over the weekend.
