Tom Cruise to appear on Top Gear

Tom Cruise's latest demanding role will be on Top Gear - as the "star in a reasonably priced car".

The Days Of Thunder actor and fellow Hollywood A-lister Cameron Diaz will each take a spin in a Kia cee'd, in a bid to complete the fastest lap they can.

Their efforts will be shown on Sunday's BBC2 show, the broadcaster confirmed.

The stars will be hoping to trounce Harry Potter star Rupert Grint, who has set the bar with his speedy lap.

Mission Impossible star Cruise and Charlie's Angels actress Diaz are in Britain to promote their new movie Knight And Day.

A glitzy UK premiere for the action comedy is taking place in London's Leicester Square today.

Cruise is known for his marathon meet and greet sessions with fans at premieres.
