I don't know the link between the 14 answers but the link for the pairs of faces is that they are related by marriage. I'm missing several names - numbers 3, 14, 15, 16, 17 and 20 (top to bottom, left to right)
13 is david puttnam. Haven't got 15, or 1 or 2. Also any of the marriage trails would save time. How the 14 are linked: I didn't get anything when I googled all 14 but when I googled just 3 I got a website of homophones, ie sound alikes, not mobiles in Old Compton Street. At first you might wonder, but think fissure, cache etc.
2 is Martin Balsam (his daughter was married to George Clooney). 1 is Jack Ashley (daughter married to Andrew Marr). Cecil B Demille (3) was Anthony Quinn's (14) father-in-law.
Thanks, i'd mistook martin balsam for frank sinatra, which had messed up the links. Now left with Peter Vaughan (?via Billie Whitelaw), ?Sacha Distel, ?Gregor Fisher (or have I got no 6 wrong, I guess they wouldn't have him in both parts) and no 15.
No, I was following macpark's suggestion, plus I'd google imaged him and thought it could be right, but not sure. Trouble with Sacha is that I don't think he links to anyone, ie not married as far as I could tell from brief look at biographies. Will look again.
Sorry, Sacha married a french ski champion francine breaud, but so far I can't find out any relatives/partners for her. I could imagine 15 is another french sports star.
Help! 15 and 20? Does anyone know their names?? I don't think it's Sacha Diestel, though admittedly I'm not sure, I can't find a picture of him that looks similar.
There's a new trail started where Peter Lawford is suggested. I wasn't sure but now having checked, as well as the Kennedy's he's linked to Dan Rowan of the laugh in, who I think is no 15. We've got it.
