Laurence Olivier's involvement in the production was by happenstance. He was in Rome to film The Shoes of the Fisherman and visited the studio where Romeo and Juliet was being shot. He asked Zeffirelli if there was anything he could do, and was given the Prologue to read, then ended up dubbing the voice of Lord Montague as well as other assorted minor roles.
