'Lost' films secret scenes in London

Lost actor Alan Dale has revealed that the hit US show has recently filmed scenes in London.

The 60-year-old - currently playing King Arthur in West End musical Spamalot - told London Lite that producers moved filming locations so they could include him in the season finale.

"I've just been doing episodes of Lost. They wanted to use me in the wrap-up of the new series," Dale said.

"I told them I couldn't because I'm doing Spamalot, so they said, 'We will build London here.' Normally they build my London sets over there."

Dale, who plays the mysterious Charles Widmore on the show, was flown out to the UK with other cast and crew where the show's US sets were rebuilt at Shepperton Studios.

The actor added that producers liked to keep a tight lid on the script, preventing any spoilers from leaking.

"I don't know what happens. They only brought my bits of script," Dale said. "It was so high-security that the wording, the title and all the headings on the scripts were changed. Only I knew they were the Lost scripts, along with the director."
