The star, who is in the U.K. capital filming latest action film All You Need Is Kill, touched down near the iconic Nelson's Column in a Royal Air Force (RAF) helicopter in full military dress.

The top tourist attraction was cordoned off and closed to the public as Cruise was joined by a number of large army tanks and extras wearing helmets and khaki ponchos.

The film, which also stars British actress Emily Blunt and Bill Paxton, is due out in 2014 and charts the story of a soldier fighting in a war with aliens.
