‍Marcus spent twelve weeks aboard the Seabourn Odyssey during her inaugural season, delivering lectures, hosting dinners, and becoming a fixture on the Liar's Club. He came back with strong reviews and a clear sense that the social life of a luxury voyage suited him as naturally as a film set.

‍

‍It's not hard to see why. He has directed Sir John Mills, Lord Attenborough, and Sir Roger Moore. He has produced music for the Athens Olympic Ceremonies alongside Björk and Tiësto. He has organised a Royal Premiere at BAFTA and hosted The Princess Royal at dinner. He has been a creative consultant to the Academy of Motion Picture Arts and Sciences. He has sculpted art suites out of ice in the Arctic and run rapids on the Yukon at twenty-one. He has a PhD, over 160 films, more than 60 international awards, and a Fellowship of the Royal Society of Arts. He has also co-hosted an evening with Stephen Fry, which suggests a certain confidence in his own ability to hold a room.

‍

‍‘Adventures in Creativity’ is Marcus's enrichment programme - a flexible series of illustrated talks, fireside chats, and dinner conversations drawn from forty years of working with Oscar winners, Royalty, Olympic composers, and the occasional iceberg.

‍

‍He is based in Beverly Hills and London, holds British citizenship and a US Green Card, and is available for sailings from October 2026.
