Camelot - 1965 London Studio Cast

After 'Camelot' opened on Broadway, the show was next seen in Australia. Paul Daneman played the part of 'Arthur' in Australia for over a year before returning to London to take over from Laurence Harvey, the original London 'Arthur', in February 1965. He continued to play the part at the Theatre Royal, Drury Lane until it gave way to 'Hello Dolly' with Mary Martin.

That is correct - it was the Australian production (scenery & costumes) that were used for the London Production. These were designed by John Truscott who later designed the movie. Jacquelyn McKeever was bought out to play Guenevere (she had just been seen on Broadwayin Oh Captain!)
