Mark Lindsay Chapman (born 8 September 1954 in London) is an English film and television actor. He is known for his roles as Chief Officer Henry Wilde in the film Titanic (1997), as John Lennon in the film Chapter 27 (2007) and as Dr. Anton Arcane on the USA Network TV series Swamp Thing from 1990 to 1993. He attended the Guildford School of Acting where he studied ballet, speech, drama, and fencing. His television credits include: Max Headroom, Dallas (as Brett Lomax), Falcon Crest (as Charley St. James), Baywatch, Murder She Wrote, Lois and Clark, JAG, Charmed, Roland Burke in The Young and the Restless, Dr. Anton Arcane (1990–1993) in Swamp Thing, and Nick Hopewell in The Langoliers. He played Chief Officer Henry Tingle Wilde in the 1997 film Titanic. A Paramount internal memo dated from 1987 has revealed that Chapman was once considered for the part of Data in Star Trek: The Next Generation. The similarity between his name and that of John Lennon's murderer, Mark David Chapman, prevented him in 1985 from playing Lennon in John and Yoko: A Love Story, a biographical film produced by NBC; Yoko Ono had been deeply involved in the production and had herself been initially impressed with his audition and approved his casting prior to discovering his full name was Mark Lindsay Chapman. She then nixed his casting on the grounds it was "bad karma", and a great deal of press attention was given to his having almost got the role (Chapman changed his name to Lindsay when he joined Equity, as there was already a Mark Chapman in the union). The role went instead to Mark McGann. Chapman's full name surfaced again when the story was published in Britain, and reporters began making inquiries about the actor, who was then working as a bricklayer with his father. Eventually Lindsay did portray Lennon, in the 2007 film Chapter 27, which had Mark David Chapman as the lead character.
