Tom Cruise and Cameron Diaz in Spain on film shoot

The two Hollywood stars have started shooting scenes that imitate the famous bull run held each year in Pamplona.

US actors Tom Cruise and Cameron Diaz have arrived in Cadiz, southern Spain to film scenes for their latest movie "Knight and Day", Spanish media reported on Sunday.

The two Hollywood stars have started shooting scenes that imitate the famous bull run held each year in Pamplona, northern Spain for the James Mangold-directed action comedy.

The Pamplona bull run is held in the city each July and was made famous by Ernest Hemingway's 1926 novel "The Sun Also Rises".

During the run, crowds race ahead of a herd of thundering bulls, which can weigh up to 700 kilogrammes (1,500 pounds) each, along an 825 metre (900 yard) course over cobbled streets.

Seven bulls escaped during the film's rehearsals earlier this month, slightly injuring two women.

"Knight and Day" is set to be released in the US in July 2010.
