Doug Ellin Premieres 'Entourage' Short in Beverly Hills (Exclusive) Entourage creator and car enthusiast Doug Ellin was visiting Cadillac's North Hollywood design center four years ago — "drooling, like he always does," says Melody Lee, Cadillac's brand director — when he was shown the automaker's Ciel concept car, a rakish convertible then making the rounds at auto shows to a rapturous reception. Ellin was no exception. The Ciel reminded Ellin of the 1965 Lincoln Continental convertible featured prominently in the HBO series's opening credits. "It was a modern version of it — I love the suicide doors," Ellin tells The Hollywood Reporter in an exclusive interview. "It's a very cool car." So cool, in fact, that Ellin says the Ciel "gave me the impetus to write the script" for the Entourage movie, which opens June 3. "The car has a big plot point," Ellin says. In the movie's backstory, volcanic agent Ari Gold — played, as in the series, by Jeremy PIven — returns to Hollywood after an unhappy retirement in Italy, bringing with him the Ciel, which he purchases as bait to lure his former meal ticket Vinnie Chase (Adrian Grenier) back into his orbit.
